Confidence Interval
A sample of n=16 scores is obtained from an unknown population. The sample has a mean of M=46 with SS=6000.
a. Use the sample data to make an 80% confidence interval estimate
of the unknown population mean.
b. Make a 90% confidence interval estimate of μ.
c. Make a 95% confidence interval estimate of μ.
d. In general, how is the width of a confidence interval related to
the percentage of confidence?
This solution gives the step by step method for computing confidence interval
