Given the following data, find the lower bound of confidence interval .Your answer must be in two decimal places.
Homework Answers
Lower bound on confidence interval :=
= mean - confidence coefficient* standard deviation / sqrt(sample size)
= 80 - 1.645*20/sqrt (100) = 80 - 3.29 = 76.71

Confidence Interval Given. Assume I created a 95% confidence interval for the mean hours studied for a test based on a random sample of 64 students. The lower bound of this interval was 4 and the upper bound was 14. Assume that when I created this interval I knew the population standard deviation. Using this information, (a) Calculate the width of the interval. (b) Calculate the margin of error for the interval. (c) Calculate the center of the interval. (d)...

A. The lower and upper bound is?
B. Interpret the interval.
Based on interviews with 92 SARS patients, researchers found that the mean incubation period was 4.5 days, with a standard deviation of 14.2 days. Based on this information, construct a 95% confidence interval for the mean incubation period of the SARS virus. Interpret the interval. The lower bound is days. (Round to two decimal places as needed.)
