A company produces a women's bowling ball that is supposed to weigh exactly 14 pounds. Unfortunately, the company has a problem

Answer: $0.2461$

Step-by-step explanation:

Given : A company produces a women's bowling ball that is supposed to weigh exactly 14 pounds.

Sample size : n=11

Degree of freedom =n-1=10

Sample standard deviation : s= 0.71 pounds

Significance level for 95% confidence interval : $\alpha=1-0.95=0.05$

We assume that the bowling ball weight is normally distributed.

Using chi-square distribution table, the required critical values are :-

$\chi^2_{df, \alpha/2}=20.48$

$\chi^2_{df, 1-\alpha/2}=3.25$

Then, the 95% confidence interval for the variance of the bowling ball weight will be :

$\dfrac{s^2(n-1)}{\chi_{\alpha/2}}$

$=\dfrac{(0.71)^2(10)}{20.48}$

∴ The 95% confidence interval for the variance of the bowling ball weight will be : $0.2461$
