HW 13.1-1 3.4 Score: 480 4:"24 answered 0 Question \"I? v A random sample of size n1 2 33 yields a standard deviation of 6.2, and a random sample of size in = 34 yields a standard deviation of 7.4. At or = 0.10, test the claim that the standard deviation of Population 1 is less than the standard deviation of Population 2. 1. The alternate hypothesis is Ha: 2. This is a left tailed test with: dfn = and dfd = 3a. The STS [to 2 decimals] is F = 3b. The P-value {to 3 decimals} is: 4a. At 0: = 0.10, the decision is: '37:} Accept Ha ""3 Reject Ho ""3? Do not reject Ho "'3' Accept Ho 4th The conclusion is: '3' There is insufficient evidence to reject the claim that 0'1 is less than 0'2 '13:? There is sufficient evidence to reject the claim that 0'1 is less than 0'2 '33:? There is insufficient evidence to support the claim that 0'1 is less than 0'2 '13:? There is sufficient evidence to support the claim that 0'1 is less than 0'2 0 Question 20 v B 0! The table below contains the results from random samples of two populations.
