<h2>Answer : (2.67, 3.53)</h2><h2></h2>

Step to step explanation:

Confidence interval for mean, when population standard deviation is unknown:

\overline{x}\pm t_{\alpha/2}\dfrac{s}{\sqrt{n}}

, where \overline{x} = sample mean

n= sample size

s= sample standard deviation

t_{\alpha/2} = Critical t-value for n-1 degrees of freedom

We assume the family size is normal distributed.

Given, n= 31 , \overline{x}=3.1, s= 1.42 ,

\alpha=1-0.9=0.10

Critical t value for \alpha/2=0.05 and degree of 30 freedom

t_{\alpha/2} = 1.697  [By t-table]

The required confidence interval:

3.1\pm ( 1.697)\dfrac{1.42}{\sqrt{31}}\\\\=3.1\pm0.4328\\\\=(3.1-0.4328,\ 3.1+0.4328)=(2.6672,\ 3.5328)\approx(2.67,\ 3.53)

Hence,  the 90% confidence interval for the estimate = (2.67, 3.53)

Mama L [17]
The percentage would be 27.5 because you add the 11, 5, 8, 7, 9 up and then divided by 11 to get your percentage. So percentage should be 27.5% and a fraction would be 11/40
