The number of hours of reserve capacity of 10 randomly selected automotive batteries is shown as follows: 1.74, 1.82, 1.58, 1.65, 1.77, 1.98, 1.39, 1.56, 1.49, 2.09.Assume the sample is taken from a normally distributed population. Construct 98% confidence intervals for (a) the population variance \(\sigma^2\) and (b) the population standard deviation \(\sigma\).(a) The confidence interval for the population variance is [ , ]. (Round to three decimal places as needed.)

Suppose that we have disjoint normal populations A and B and we want to find the standard error estimate for estimating the difference in their means. We have an IRS from A of size 9 and an IRS from B of size 4. The POOLED variance is 18.72. What is the MARGIN OF ERROR for the 99 percent confidence interval for the difference of population means if we assume both populations have the same population variance? Group of answer choices
