To determine

Identify the percent of values that must be chopped off from each tail for the confidence interval of 95%.

a.

Expert Solution

Answer to Problem 104E

The percent of values that must be chopped off from each tail is 2.5%.

Explanation of Solution

In a 95% confidence interval, 95% of observation will be considered as the middle values and the remaining 5% of values has to be chopped off from both sides of the tail. Thus, from each tail, 2.5%(=5%2) of values has to be chopped off.
