A study is done to explore the effects of light on mood. Testing is done for 15 subjects and results in a sample mean of 7.5 on a mood scale of 1-10. The standard deviation is 1.5 and the standard error of 0.387. Use the intermediate data to construct a 95% confidence interval. (Round to the nearest thousandth)

The quality control manager at a light-bulb factory needs to
estimate the mean life of a new type of light-bulb. The population
standard deviation is assumed to be 65 hours. A random sample of 40
light-bulbs shows a sample mean life of 505 hours. Construct and
explain a 95% confidence interval estimate of the population mean
life of the new light-bulb.
what size sample would be needed to achieve a margin of error of
15 hours or less?

You are given the sample mean and the population standard
deviation. Use this information to construct the 90% and 95%
confidence intervals for the population mean. Interpret the results
and compare the widths of the confidence intervals. If convenient,
use technology to construct the confidence intervals.

A study was done on proctored and nonproctored tests. The
results are shown in the table. Assume that the two samples are
independent simple random samples selected from normally
distributedpopulations, and do not assume that the population
standard deviations are equal. Use a 0.05 significance level for
both parts.
Proctored: n = 33, x bar = 77.98, s = 10.44
Nonproctored: n = 31, x bar = 81.95, s = 20.69
