Answer:
11 : 22 : 132
Step-by-step explanation:
1 + 2 + 12 = 15
165 ÷ 15 = 11
1 × 11 = 11
2 × 11 = 22
12 × 11 = 132
11 : 22 : 132
Answer: (1.64,4.01)
Step-by-step explanation:
The confidence interval for the population variance is given by :-
Given : n= 69 ;
Significance level :
Using Chi-square distribution table ,
[by using chi-square distribution table]
Now, the 95% confidence interval for the standard deviation of the height of students at UH is given by :-
Hence, the 99% confidence interval for the population variance of the weights of all axles in this factory is (1.64,4.01).
