Explanation:
Let x be a random variable that represent the number of years of education.
Given: Sample size : n= 26
Sample mean : 
Sample standard deviation : s = 3.22
Significance level :

and df = 25 will be
90% confidence interval for mean:
A 90% confidence interval for the mean number of years of education = (11.95, 14.11)
