Using the Poisson and the normal distributions, the probabilities are given as follows:
a) 0.0895 = 8.95%.
b)
Without correction, P(X < 8) = 0.1251 = 12.51%.
With continuity correction, P(X < 8) = 0.0968 = 9.68%.
c)
Without correction, P(16 < X < 24) = 0.1248.
With correction, P(16 < X < 24) = 0.1558 = 15.58%.
What is the Poisson distribution?In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by:
[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]
The parameters are:
x is the number of successese = 2.71828 is the Euler number[tex]\mu[/tex] is the mean in the given interval.In this problem, the mean is given by:
[tex]\mu = 12[/tex]
Hence the probability that X is less than 8 is given by:
P(X < 8) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) + P(X = 6) + P(X = 7).
In which:
[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]
[tex]P(X = 0) = \frac{e^{-12}12^{0}}{(0)!} = 0.00001[/tex]
...
[tex]P(X = 7) = \frac{e^{-12}12^{7}}{(7)!} = 0.04368[/tex]
The middle values are found applying the same formula, and adding them, the probability is given by:
P(X < 8) = 0.0895 = 8.95%.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.The Poisson distribution can be approximated to the normal with [tex]\sigma = \sqrt{\mu}[/tex]Without continuity correction, the probability that X is less than 8 is the p-value of Z when X = 8, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{8 - 12}{\sqrt{12}}[/tex]
Z = -1.15
Z = -1.15 has a p-value of 0.1251.
Hence:
Without correction, P(X < 8) = 0.1251 = 12.51%.
With continuity correction, as the Poisson distribution is discrete and the normal is continuous, the probability is P(X < 7.5), which is the p-value of Z when X = 7.5, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{7.5 - 12}{\sqrt{12}}[/tex]
Z = -1.3
Z = -1.3 has a p-value of 0.0968.
Hence:
With continuity correction, P(X < 8) = 0.0968 = 9.68%.
For item c, without correction, the probability is the p-value of Z when X = 24 subtracted by the p-value of Z when X = 16, hence:
X = 24:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{24 - 12}{\sqrt{12}}[/tex]
Z = 3.46
Z = 3.46 has a p-value of 0.9997.
X = 16:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{16 - 12}{\sqrt{12}}[/tex]
Z = 1.15
Z = 1.15 has a p-value of 0.8749.
0.9997 - 0.8749 = 0.1248.
Hence:
Without correction, P(16 < X < 24) = 0.1248.
With correction, the probability is the p-value of Z when X = 23.5 subtracted by the p-value of Z when X = 15.5, hence:
X = 23.5:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{23.5 - 12}{\sqrt{12}}[/tex]
Z = 3.32
Z = 3.32 has a p-value of 0.9996.
X = 15.5:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{15.5 - 12}{\sqrt{12}}[/tex]
Z = 1.01
Z = 1.01 has a p-value of 0.8438.
0.9996 - 0.8438 = 0.1558.
Hence:
With correction, P(16 < X < 24) = 0.1558 = 15.58%.

Step-by-step explanation:
Consider two neighboring island countries called Contente and Euphoria. They each have 4 million labor hours available per week that they can use to produce jeans, rye, or a combination of both. The following table shows the amount of jeans or rye that can be produced using 1 hour of labor.
Country Jeans Rye
Contente 5 10
Euphoria 4 16
Initially, suppose Contente uses 1 million hours of labor per week to produce jeans and 3 million hours per week to produce rye, while Euphoria uses 3 million hours of labor per week to produce jeans and 1 million hours per week to produce rye. Consequently, Contente produces 5 million pairs of jeans and 30 million bushels of rye, and Euphoria produces 12 million pairs of jeans and 16 million bushels of rye. Assume there are no other countries willing to trade goods, so, in the absence of trade between these two countries, each country consumes the amount of jeans and rye it produces.
Contente's opportunity cost of producing 1 pair of jeans is ___ of rye, and Euphoria's opportunity cost of producing 1 pair of jeans is ___ of rye. Therefore ___ has a comparative advantage in the production of jeans, and ___ has a comparative advantage in the production of rye.
Suppose that each country completely specializes in the production of the good in which it has a comparative advantage, producing only that good. In this case, the country that produces jeans will produce ___ million pairs per week, and the country that produces rye will produce ___ million bushels per week.
n the following table, enter each country's production decision on the third row of the table (marked “Production”).
Suppose the country that produces jeans trades 13 million pairs of jeans to the other country in exchange for 39 million bushels of rye.
In the following table, select the amount of each good that each country exports and imports in the boxes across the row marked “Trade Action,” and enter each country's final consumption of each good on the line marked “Consumption.”
When the two countries did not specialize, the total production of jeans was 17 million pairs per week, and the total production of rye was 46 million bushels per week. Because of specialization, the total production of jeans has increased by ___ million pairs per week, and the total production of rye has increased by ___ million bushels per week.
1. Euphoria's opportunity cost of producing a a bushel of rye is 4 pairs of jeans.
Contentes opportunity cost of producing a bushel of rye is 2 pairs of jeans.
2. Contente has comparative advantage in producing rye
Euphoria has comparative advantage in jeans production
How to find the opportunity Cost?For Euphoria:
The opportunity cost of producing a unit of rye in terms of jeans is;
Opportunity Cost = 20/5 = 4
For contente:
The opportunity cost of producing a unit of rye in terms of jeans is;
Opportunity Cost = 16/8 = 2
The opportunity cost of producing 1 unit of jean in terms of unit of rye:
For euphoria = 5/20 = 1/4
For contente = 8/16 = 1/2
1. Euphoria's opportunity cost of producing a a bushel of rye is 4 pairs of jeans.
Contentes opportunity cost of producing a bushel of rye is 2 pairs of jeans.
2. Contente has comparative advantage in producing rye
Euphoria has comparative advantage in jeans production
3. Contente produces 8 bushels of rye so with 4 million hours of labor = 8x4 = 32 million bushels in a week.
Euphoria 20 pairs of jean in a week, using 4 million hours of labor. 20x4 = 80 pairs of jean a week

We have,
m∠1 = (x+38)° andm∠2 = 3x°∵ From figure m∠1 and m∠2 divided 90° into two parts
∴ m∠1 + m∠2 = 90° ----------------------(1)
Now putting the values of m∠1 and m∠2 in equation (1)
m∠1 + m∠2 = 90° ----------------------(1)
(x+38)° + 3x° = 90°
x°+38° + 3x° = 90°
4x° = 90° - 38°
4x° = 52°
x° = (52/4)°
x° = 13°
So,
m∠1 = (x+38)°

Mean = 0.5545, Median =0.57, Mode = 0.79 of the following data.
What is mean median and mode?
A data set's mean (average) is calculated by summing all of the numbers in the set, then dividing by the total number of values in the set. When a data collection is ranked from least to greatest, the median is the midpoint. The number that appears most frequently in a data set is called the mode.For the given data 0.29, 0.3, 0.34, 0.35, 0.37, 0.46, 0.51, 0.51, 0.52, 0.57, 0.57, 0.58, 0.62, 0.63, 0.65, 0.68, 0.77, 0.79, 0.79, 0.79.
The mean is calculated as:
Mean = (0.29 + 0.3 + 0.34 + 0.35 + 0.37 + 0.46 + 0.51 + 0.51 + 0.52 + 0.57 + 0.57 + 0.58 + 0.62 + 0.63 + 0.65 + 0.68 + 0.77 + 0.79 + 0.79 + 0.79)/20
= 11.09/20
Mean = 0.5545
Median is the middle value of the data set and since the sample size is even which is 20 hence the median is found between n/2 and n/2 +1 which is 10th value and 11th value when the data set is arrange in ascending order.
so, the 10th value is 0.57 and 11th value is also 0.57 so, the median is (0.57 + 0.57)/2 = 0.57
Median:
The median is the most occuring value in the dataset and as we can see that 0.79 appeared 3 times hence 0.79 is Mode.
So, finally:
Mean = 0.5545
Median =0.57
Mode = 0.79
