Answer:
The computer-controlled system would likely be better than the manual system used by the publishing company in several ways:
Precision: The computer-controlled system would be more precise and accurate than manual cutting. It can measure and cut the paper rolls with greater accuracy, reducing the likelihood of errors or waste.
Efficiency: The computer-controlled system can cut the paper rolls faster and more efficiently than manual cutting. This would increase the productivity of the workers and enable the company to produce more products in less time.
Consistency: The computer-controlled system would ensure consistent quality of the cut paper rolls. This is because the machine is programmed to cut the paper in the exact same way every time, which means that there is less room for human error or variation.
Safety: The computer-controlled system would be safer for the workers than manual cutting. It reduces the risk of injury from accidents or repetitive strain injuries associated with manual cutting.
Overall, the computer-controlled system would provide significant benefits for the publishing company in terms of precision, efficiency, consistency, and safety.
Explanation:
Let's assume that, over the years, a paper and pencil test of anxiety yields a mean score of 35 for all incoming college freshmen. We wish to determine whether the scores of a random sample of 20 new freshmen, with a mean of 30 and a standard deviation of 10, can be viewed as coming from this population. Test at the .05 level of significance.
The scores of the random sample (mean = 30) cannot be viewed as coming from the population with a mean of 35.
To determine whether the scores of the random sample of 20 new freshmen can be viewed as coming from the population with a mean score of 35, we can conduct a hypothesis test using the t-test. Null hypothesis (H₀): The sample mean is equal to the population mean (µ = 35).Alternative hypothesis (H₁): The sample mean is not equal to the population mean (µ ≠ 35).With a sample size of 20, we can use the t-distribution for inference. Using a significance level of .05, which corresponds to a 95% confidence level, we compare the calculated t-value to the critical t-value from the t-distribution table.The calculated t-value can be found using the formula: t = (sample mean - population mean) / (sample standard deviation / sqrt(sample size)).In this case, t = (30 - 35) / (10 / sqrt(20)) ≈ -2.24.The critical t-value can be found using the degrees of freedom (df = sample size - 1). For df = 19 and a two-tailed test, the critical t-value is approximately ±2.093.Since the calculated t-value (-2.24) is beyond the critical t-value (-2.093), we reject the null hypothesis. We have evidence to suggest that the scores of the random sample do not come from the population with a mean score of 35.For more such questions on Scores:

The null hypothesis that the sample mean is equal to the population mean of [tex]35[/tex] is rejected in favor of the alternative hypothesis, suggesting a significant difference, as the calculated t-value of -[tex]-2.82[/tex] falls beyond the critical t-value range at the [tex]0.05[/tex] level of significance.
To determine whether the scores of the random sample of [tex]20[/tex] new freshmen can be viewed as coming from the population with a mean score of [tex]35[/tex], a one-sample t-test can be conducted at the [tex]0.05[/tex] level of significance. The null hypothesis states that the sample mean is equal to the population mean, while the alternative hypothesis suggests a significant difference. Calculating the t-value using the sample mean ([tex]30[/tex]), population mean ([tex]35[/tex]), sample standard deviation ([tex]2.82[/tex]), and sample size (√[tex]20[/tex]), the calculated t-value is -[tex]2.82[/tex]. With a critical t-value of approximately ±[tex]2.093[/tex] for a two-tailed test at α = [tex]0.05[/tex], the calculated t-value falls beyond this range. Thus, the null hypothesis is rejected, indicating that the sample means are significantly different from the population mean of [tex]35[/tex], suggesting that the random sample does not come from the same population.In conclusion, based on the calculated t-value of [tex]-2.82[/tex], which falls beyond the critical t-value range, we reject the null hypothesis and conclude that the scores of the random sample of [tex]20[/tex] new freshmen, with a mean of [tex]30[/tex] and a standard deviation of [tex]10[/tex], cannot be viewed as coming from the population with a mean score of [tex]35[/tex] at the [tex]0.05[/tex] level of significance.

Fidelity credit union, a mean of five customers arrives hourly at the drive-through window what is the probability that in any hour, less than one customer will rise on your answer to 4 Decimal Pl. Pl.
This scenario follows a Poisson distribution since the arrivals of customers can be considered random and occur at a constant average rate. The formula for the Poisson distribution is:
P(X = x) = (e^(-λ) * λ^x) / x!
where P(X = x) is the probability of x events occurring in a given time period, λ is the mean number of events per time period, and x is the number of events.
In this case, λ = 5 since the mean number of customers arriving hourly is 5.
To find the probability of less than one customer arriving in an hour, we need to calculate P(X < 1).
P(X < 1) = P(X = 0) + P(X = 1)
P(X = 0) = (e^(-5) * 5^0) / 0! = e^(-5) = 0.0067 (rounded to 4 decimal places)
P(X = 1) = (e^(-5) * 5^1) / 1! = 0.0337 (rounded to 4 decimal places)
Therefore,
P(X < 1) = 0.0067 + 0.0337 = 0.0404 (rounded to 4 decimal places)
So, the probability of less than one customer arriving in an hour at Fidelity credit union is 0.0404.
