b,c- see details below
Step-by-step explanation:
a. #Use shapiro test to test for normality
Yes. The population has a p-value greater than 0.05:
0.05469>0.05
b.From our output, the 98% intervals are:
[8.19016,9.648021]
c. The new interval, [8.19016,9.648021] is wider, but we are more confident that it contains the true mean ( 8.919091)
