Expert Solution

critical value tα/2 for sample size(n) = 15 and 98% confidence level is

level of significance = 1 - 0.98 = 0.02

degree of freedom = n -1 = 15 - 1 = 14

Hence in t table we will look for value with level of significance = 0.02 (Two tails) and degree of freedom = 14

which is equal to 2.6245.

option A is correct.
