Problem 2

Determine whether the distribution is a discrete probability distribution. If not, state why.

Step-by-Step Solution:

Step 1 of 5) Determine whether the distribution is a discrete probability distribution. If not, state why. Test Hypotheses Regarding Two Population Standard Deviations Now that we know the approximate sampling distribution of s2 1 s2 2 and how to find critical values in the F-distribution, we can introduce a procedure that can be used to test hypotheses regarding two population standard deviations (or variances). Test Hypotheses Regarding Two Population Standard Deviations To test hypotheses regarding two population standard deviations, s1 and s2, use the following steps, provided that 1. the samples are obtained using simple random sampling or through a randomized experiment. 2. the sample data are independent. 3. the populations from which the samples are drawn are normally distributed. Step 1 Determine the null and alternative hypotheses.
