Use technology to construct the confidence intervals for the population variance sigmaσsquared2 and the population standard deviation sigmaσ. assume the sample is taken from a normally distributed population. cequals=0.99, sequals=35, nequals=19the confidence interval for the population variance is ( nothing, nothing).

(593.44, 3519.67).

Step-by-step explanation:

As per given , we have

Confidence level :

Significance level :

Sample size : n= 19

Sample standard deviation : s= 35

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

Now, the Confidence interval for the population variance is given by :-

Hence, the confidence interval for the population variance is (593.44, 3519.67).

-4

step-by-step explanation:

do 6-10=

if u need it to be negative.
