Expert Answer

Step 1

Given information:

Sample size (n) = 14

Sample mean=25

Sample standard deviation=6

Step 2

Confidence level=95%

So,

Significance level=1- Confidence level

                            =1-95%

                            =1-0.95

                            =0.05

Degree of freedom=n-1

                             =14-1

                             =13

Step 3

Using t-table, the value of t-critical at 0.05 significance levels and 13 degre...
