To evaluate the effect of a treatment, a sample is obtained and a treatment is administered to the individuals in the sample. After treatment, the sample mean is found to be X = 14.8 with a standard deviation of a = 4.1. Construct a 95% confidence interval for μ, the population mean for the treatment group, assuming the sample contains: (a) N = 15 individuals. (b) N = 30 individuals. (c) Comparing your answers for parts (a) and (b), how does the size of the sample influence the width of your confidence interval for µ?

In a random sample of 24 people, the mean commute time to work was 34.7 minutes and the standard deviation was 7.2 minutes. Assume the population is normally distributed and use a t-distribution to construct a 99% confidence interval for the population mean u. What is the margin of error of u? Interpret the results. The confidence interval for the population mean µ is ( D (Round to one decimal place as needed.) The margin of error of u is. (Round to one decimal place as needed.) Interpret the results. O A. With 99% confidence, it can be said that the population mean commute time is between the bounds of the confidence interval. O B. It can be said that 99% of people have a commute time between the bounds of the confidence interval. OC. With 99% confidence, it can be said that the commute time is between the bounds of the confidence interval. O D. If a large sample of people are taken approximately 99% of them will have commute times between the bounds of the confidence interval.
Assume that we want to construct a confidence interval. Do one of the following, as appropriate: (a) find the critical value ta/2. (b) find the critical value z/2, or (c) state that neither the normal distribution nor the t distribution applies. The confidence level is 95%, o is not known, and the histogram of 62 player salaries (in thousands of dollars) of football players on a team is as shown.
The manager at a large fitness center keeps track of the amount of time it takes a sample of 65 clients to run a mile. She finds that the mean time to run a mile in this sample is x = 10.4 minutes and the standard deviation is s = 2.1 minutes. Assuming the sample is a simple random sample of all clients at this particular fitness center, find a 95% confidence interval H, the unknown mean running time of all clients from the fitness center. for (Give your answer as an interval in the form (lower limit, upper limit). Use decimal notation. Give the limits to two decimal places.) 95% confidence interval:
What Proportion of Americans Say They Are Poor? A survey of 1000 US Adults conducted in October 2019 found that 182 of them described themselves as poor. In Exercise 3.128, we used a bootstrap distribution to find a 90% confidence interval for the proportion of all US adults who would describe themselves as poor. Here, we find this 90% confidence interval using the normal distribution and a formula for the standard error, as follows: (a) Give value for the sample statistic.Value = . (b) Find the standard error for this sample statistic. Round to three decimal places. (c) What is z* for a 90% confidence interval? Round to three decimal places. (d) Use the results of (a), (b), and (c) to find the 90% confidence interval. Round to three decimal places. to
An agriculture publication claims that the population mean of the birth weights for all Herdwick sheep is 4.62 kg. A veterinary service has hired you to test that claim. To do so, you select a random sample of 35 Herdwick sheep and record the birth weights. Assume it is known that the population standard deviation of the birth weights of Herdwick sheep is 2.15 kg. Based on your sample, follow the steps below to construct a 95% confidence interval for the population mean of the birth weights for all Herdwick sheep. Then state whether the confidence interval you construct contradicts the publication's claim. (If necessary, consult a list of formulas.)

Work Time Lost due to Accidents At a large company, the Director of Research found that the average work time lost by employees due to accidents was 102 hours per year. She used a random sample of 21 employees. The standard deviation of the sample was 5.4 hours. Estimate the population mean for the number of hours lost due to accidents for the company, using a 99% confidence interval. Assume the variable is normally distributed. Use a graphing calculator and round the answers to the nearest whole number.
