An agronomist would like to estimate the average weight of all Indian River County oranges. The meanweight of a random sample of 141 Indian River County oranges was found to be 173 grams. The standarddeviation of the weights of all Indian River County oranges is known to be 13 grams.Find three different confidence intervals - one with a 97% confidence level, one with a 96% confidencelevel, and one with a 90% confidence level - for the mean weight of all Indian River County oranges. Noticehow the confidence level affects the margin of error and the width of the interval.Report confidence interval solutions using interval notation. Round solutions to two decimal places, ifnecessary.The margin of error for a 97% confidence interval is given by EA 97% confidence interval is given by=

A researcher wants to compare the effectiveness of two different study techniques for a test. The mean test score for the first technique is 75 with a standard deviation of 5, and the mean test score for the second technique is 80 with a standard deviation of 4.

A food snack manufacturer samples 15 bags of pretzels off the assembly line and weighed their contents. If the sample mean is 10.2 and the sample standard deviation is 0.25, find the 95% confidence interval of the true mean.
A group of 78 people enrolled in a weight-loss program that involved adhering to a special diet and to a daily exercise program. After six months, their mean weight loss was 25 pounds, with a sample standard deviation of 9 pounds. A second group of 43 people went on the diet but didn’t exercise. After six months, their mean weight loss was 14 pounds, with a sample standard deviation of 7 pounds. Find a 95% confidence interval for the mean difference between the weight losses.
From the scores in subject statistics for 8 students, it was found that the mean score is 73 and the standard deviation is 5.15. Construct a 95% confidence interval estimate for the mean score of all students in the class.
A doctor claims that the mean number of hours of sleep that seniors in high school get per night differs from the mean number of hours of sleep college seniors get per night. To investigate, he selects a random sample of 50 high school seniors from all high schools in his county. He also selects a random sample of 50 seniors from the colleges in his county. He constructs a 95% confidence interval for the true mean difference in the number of hours of sleep for seniors in high school and seniors in college. The resulting interval is (0.57, 1.25). Based upon the interval, can the doctor conclude that mean number of hours of sleep that seniors in high school get per night differs from the mean number of hours of sleep college seniors get per night? yes because 1 is in the confidence interval yes because 0 is not in the confidence interval no because 1 is in the confidence interval no because 0 is not in the confidence interval
An instructor gives two students portions of the same ore sample to examine by gravimetric analysis. Student number 1 gets the following results for the iron content for this sample: 35.1, 33.8, and 34.5 mg/g. Student number 2 obtains values of 32.4, 33.1, and 32.7 mg/g. Are the mean results obtained by these two students the same at the 95% confidence interval? 3)
Two types of valves are being tested to determine if there is a difference in pressure tolerances. Fifteen out of a random sample of 100 of Valve A cracked under 4,500 psi.

A pharmaceutical company is running tests to see how well its new drug lowers cholesterol. Fourteen adults volunteer to participate in the study. The total cholesterol level of each participant (in mg/dL) is recorded once at the start of the study and then again after three months of taking the drug. The results are given in the following table. Construct a 90%90% confidence interval for the true mean difference between the cholesterol levels for people who take the new drug. Let Population 1 be the initial cholesterol level and Population 2 be the cholesterol level after three months. Round the endpoints of the interval to one decimal place, if necessary.
