A survey asked 26 adults how many years of education they had. The sample mean was 13.03 with a standard deviation of 3.22. It i
yulyashka [42]

Answer: (11.95, 14.11)

Explanation:

Let x be a random variable that represent the number of years of education.

Given: Sample size : n= 26

Sample mean : \overline{x}=13.03

Sample standard deviation : s = 3.22

Significance level : \alpha=100\%-90\%=10\%=0.1

Degree of freedom: df = n-1 = 25

Critical t-value for \alpha=0.1 and df = 25 will be

t_{\alpha/2, df}=t_{0.05,25}=1.7081

90% confidence interval for mean:

\overline{x}\pm t_{\alpha/2,df}\dfrac{s}{\sqrt{n}}\\\\=13.03\pm (1.7081)\dfrac{3.22}{\sqrt{26}}\\\\=13.03\pm  (1.7081)\dfrac{3.22}{5.09902}\\\\=13.03\pm 1.08\\\\=(13.03-1.08,\ 13.03+1.08)\\\\ =(11.95,\ 14.11)

A 90% confidence interval for the mean number of years of education = (11.95, 14.11)

iris [78.8K]
No, he was not hypocritical because he didn't allow slavery. With or without it, it wouldn't have had a big impact on his life so he didn't do it because it helped himself. He did because he had the kindness of heart.
