An article reports that in a sample of 7 men, the average volume of femoral cartilage (located in the knee) was 18.7 cm3 with a standard deviation of 3.3 cm3 and the average volume in a sample of 9 women was 11.2 cm3 with a standard deviation of 2.4 cm2. Let μXμX represent the population mean for men and let μYμY represent the population mean for women. Find a 95% confidence interval for the difference μX−μYμX−μY .
A random sample of size 15 taken from a normally distributed population revealed a sample mean of 75 and a sample variance of 25. The upper limit of a 95% confidence interval for the population mean would equal?
In the year 2017, the mean and standard deviation for the quality grade point average of the first-year students in a basic statistics course is found to be 2.95 and 0.53. If 38 undergraduates are randomly selected, find the 95% confidence interval for the mean of the entire group. Within the same year, if another group of 38 students were sampled and resulted with a mean of 2.87, test the hypothesis that the sample mean is different from the population mean at a 5% level of significance.
Suppose that the population standard deviation of student scores is 20. What will be the sample size so that the resulting 90% confidence interval for the population mean score has a margin of error no larger than 4?

A research scholar wants to know how many times per hour a certain strand of virus reproduces. He wants to construct the 80% confidence interval with a maximum error of 0.15 reproductions per hour. Assuming the population standard deviation is known to be 2.13, what is the minimum sample size required for the estimate?
An article presents the results of a study in which the weights of 295 eggs from 27 week-old breeding hens averaged 54.1 g with a standard deviation of 4.4 g, and weights of 295 eggs from 59 week-old hens averaged 72.7 g with a standard deviation of 4.7 g. Let μXμX represent the population mean weight for 59-week-old hens and let μYμY represent the population mean weight for 27-week-old hens. Find a 95% confidence interval for the difference μX−μYμX−μY .
A simple random sample from a population with a normal distribution of 104 body temperatures has x=98.70°F and s=0.62°F. Construct a 90% confidence interval estimate of the standard deviation of body temperature of all healthy humans. Is it safe to conclude that the population standard deviation is less than 0.80°F?
A report in a research journal states that the average weight loss of people on a certain drug is 17 lbs with a margin of error of ±3 lbs with confidence level C = 95%. (a) According to this information, the mean weight loss of people on this drug, μ, could be as low as ________ lbs. (b) If the study is repeated, how large should the sample size be so that the margin of error would be less than 1.5 lbs? (Assume σ= 6 lbs.)
1 Suppose that the average time spent per day with digital media several years ago was 3 hours and 22 minutes. For last year, a random sample of 20 adults in a certain region spent the numbers of hours per day with digital media given in the accompanying table. Preliminary data analyses indicate that the t-interval procedure can reasonably be applied. Find and interpret a 90% confidence interval for last year's mean time spent per day with digital media by adults of the region. (Note: x=5.88hr and s=2.27hr.) The 90% confidence interval is from ( ? ) hour(s) to ( ? )hour(s). Interpret the 90% confidence interval. Select all that apply. A. There is a 90% chance that the mean amount of time spent per day on digital media last year by all adults in the region is between the interval's bounds. B.With 90% confidence, the mean amount of time spent per day on digital media last year by all adults in the region is between the interval's bounds. C.90% of all…
