Question
STATDISK has the ability to find test statistics, critical values, and p values when testing hypotheses about two population standard deviations and variances. The next questions are designed to introduce you to these functions within STATDISK.
The two population standard deviation hypothesis test function is located under the “analysis,” “hypothesis testing,” and “standard deviation two samples” sub menu.
The claim being tested is σ1=σ2 with a 9.17% significance level. A first sample of size 96 with a sample mean of 270 and a sample standard deviation of 40 and a second sample of size 259 with a sample mean of 256 and a sample standard deviation of 32 are used to test the claim.
What is the p-value? (Round to the nearest ten-thousandth.)
