A sample of 40 individuals at a shopping mall found that the mean number of visits to a restaurant per week was 2.88 with a standard deviation of 1.59. Find a 99% confidence interval for the mean num-ber of restaurant visits. Use the appropriate formula and verify your result using the Confidence Intervals workbook.

Answers

Answer 1

Answer:

The confidence interval is between 2.23 and 3.53

Explanation:

The confidence interval (C) = 99% = 0.99

α = 1 - C = 1 - 0.99 = 0.01

α/2 = 0.01/2 = 0.005

The z score of α/2 corresponds to the z score of 0.495 (0.5 - 0.005) which is 2.576

The margin of error (E) is given as:

[tex]E=z_{\frac{\alpha}{2} }*\frac{\sigma}{\sqrt{n} }\\\\where\ n=sample\ size,\sigma=standard\ deviation\\\\Given\ that\ \sigma=1.59,n=40,z_{\frac{\alpha}{2} }=2.576\ hence: \\\\E=2.576*\frac{1.59}{\sqrt{40} } =0.65[/tex]

The confidence interval = mean ± margin of error = 2.88 ± 0.65 = (2.23, 3.53)

The confidence interval is between 2.23 and 3.53

Martin Company currently produces and sells 40,000 units of product at a selling price of $12. The product has variable costs of $6 per unit and fixed costs of $150,000. The company currently earns a total contribution margin of: ________.
a. $280,000
b. $200,000
c. $240,000
d. $90,000

Answers

Answer:Total contribution margin = $240,000---c

Explanation:

Contribution margin is the revenue left after removing  the variable costs that are incurred in producing a product. This  margin helps one to know how profitability each  item is  that a company produces and  puts up for sale.

It is calculated as

 Contribution per unit = selling price per unit - variable costs per unit.

$12-$6 = $6

Total contribution margin = Contribution per unit x number of units sold.

$6 x 40,000 units

=  $240,000

A deposit of $1000 is made in a bank account that pays 24% interest per year compounded quarterly. Approximately how much money will be in the account after 10 years

Answers

Answer:

$10,285.72

Explanation:

In this scenario, we can use the compound interest formula to calculate the total after 10 years. The formula is the  A = P * [tex](1 + r/n)^{nt}[/tex]

where,

A = final value after interest

P = initial investment amount

r = annual interest rate in decimal form

n = number of time the interest is compounded based on t

t = total amount of time

In this case, the interest is compounded quarterly meaning 4 times a year, therefore we can plug all the values into the formula and solve for A

A = P * [tex](1 + r/n)^{nt}[/tex]

A = 1000 * [tex](1 + 0.24/4)^{4*10}[/tex]

A = 1000 * [tex](1.06)^{40}[/tex]

A = 1000 * 10.2857

A = 10,285.72

Therefore after 10 years the account will have a total of $10,285.72

What is the value today of receiving $5,000 at the end of six years, assuming an interest rate of 8% compounded semiannually?

Answers

Answer:

$3,122.96

Explanation:

Future value = 5000

i = 8%

n = 6

m = 2

Present Value = FV(1+i/m)^mn

Present Value = 5,000(1+0.08/2)^-2*6

Present Value = 5,000(1.04)^-12

Present Value = 5,000 / (1.04)^12

Present Value = 5,000 / 1.6010322

Present Value = 3122.985284118583

Present Value = $3,122.96

Answers

Answer:

the post money valuation of the company is $1,750,000

Explanation:

The computation of the post money valuation is shown below:

Given that

Value of 400,000 shares is  $1 million.

So,

The Value of 1 share is

= $1 million ÷ 400,000

= $2.5

And,  

Total number of shares is

= 400,000 + 200,000 + 100,000

= 700,000

Now  

Total value of shares is

= $2.5 × 700,000

= $1,750,000

hence, the post money valuation of the company is $1,750,000

June Corp. sells one product and uses a perpetual inventory system. The beginning inventory consisted of 100 units that cost $20 per unit.

Answers

Answer:

Ending inventory in units= 230

Explanation:

Giving the following information:

Beginning inventory= 100 units

Purchases= 580 units

Sales during the month totaled 450 units

To calculate the ending inventory in units, we need to use the following formula:

Ending inventory in units= total units - units sold

Ending inventory in units= 680 - 450

Ending inventory in units= 230

Dufner Co. issued 14-year bonds one year ago at a coupon rate of 7.9 percent. The bonds make semiannual payments. If the YTM on these bonds is 5.6 percent, what is the current dollar price assuming a par value of $1,000

Answers

Answer:

Bond price= $1,210.4

Explanation:

Giving the following information:

Coupon rate= 0.079/2= 0.0395

YTM= 0.056/2= 0.028

Face value= $1,000

n= 13*2= 26

To calculate the price of the bond, we need to use the following formula:

Bond Price​= cupon*{[1 - (1+i)^-n] / i} + [face value/(1+i)^n]

Bond price= 39.5*{[1 - (1.028^-26)]/0.028} + [1,000 / 1.028^26]

Bond price= 722.67 + 487.73

Bond price= $1,210.4

c. $9,937.52
d. $8,632.13
e. $7,326.74

Answers

Answer: c. $9,937.52

Explanation:

The Accounts receivable balance can be calculated by;

= Outfits per years * Average Price * (Collection period/365)

Collection period;

71% take the discount which means that they pay in 15 days while the rest pay in 40.

= (71% * 15) + (29% * 40)

= 22.25 days

Accounts Receivable balance = 1,140 * 143 * (22.25/365)

= $9,937.52

Jessica paid more tax than she needed to because she made a mistake on her tax returns. Here's a list of things she can do to correct her mistake:

A) Wait for IRS correction.

What is IRS correction?

IRS, or the Internal Revenue System, might rectify the miscalculation and notify Jessica about the same through a letter. In that case, IRS will intimate Jessica about the changes along with the list of steps she needs to follow to fix the mistake.

B) Fill out the 1040X form.

What is Form 1040X?

In case Jessica doesn't want to wait for IRS to fix the mistake, she can correct it by herself. Jessica can apply to rectify her mistake through form 1040X. It is the only form she can file to correct the previous mistake on her tax returns. The form can be downloaded as a pdf and is easy to fill. It acts as a rectification to form numbers 1040, 1040A, 1040EZ, 1040NR, and 1040NR-EZ. She should not apply for a new 1040. However, Jessica should keep a copy of 1040 with her.

There are three columns in form 1040X. Jessica needs to sum up the original 1040 in the first column. In the second column, Jessica needs to highlight the modification. Jessica will have to write the amount she originally had to pay.

How should Jessica support her claims?

Jessica should explain her situation clearly in part three of the form. She should also attach the relevant documents to support her claim.

How to get a refund?

Jessica must file the 1040X in two to three years to receive a refund on her overpayment.
