The data sets represent simple random samples from a population whose mean is 100.

(a) Compute the sample mean of each data set.
(b) For each data set, construct a 95% confidence interval about the population mean.
(c) What effect does the sample size n have on the width of the interval?For parts (d)€“(e), suppose that the data value 106 was accidentally recorded as 016.
(d) For each data set, construct a 95% confidence interval about the population mean using the incorrectly entered data.
(e) Which intervals, if any, still capture the population mean, 100? What concept does this illustrate?
