T he following sample of 16 measurements, saved in the LM5_34 file, was selected from a population that is approximately normally distributed:
91 | 80 | 99 | 110 | 95 | 106 | 78 | 121 | 106 | 100 |
97 | 82 | 100 | 83 | 115 | 104 |
|

|
a. Construct an 80% confidence interval for the population mean.
b. Construct a 95% confidence interval for the population mean, and compare the width of this interval with that of part a.
c. Carefully interpret each of the confidence intervals, and explain why the 80% confidence interval is narrower.
