Question

QUESTION 2 Two samples are randomly selected from populations that are normally distributed The sample statistics are given below: n1 = 25 n2 = 30 S12 = 6.498 S22 = 4.05 If we test the claim that 12-22, what will be the p-value? O 0.2241 .0405 O 1.604 0.623 QUESTION 3 Two samples are randomly selected from populations that are normally distributed The sample statistics are given below: n1 = 13 n2 = 12 s1233.32 2226.565 If we test the claim that 12 22, what will be the p-value? 1.57 .7144 0-0125 O 0.797

Explanation / Answer

Answer - 2: The statistical software output for this problem is:

Two sample variance summary hypothesis test:
12 : Variance of population 1
22 : Variance of population 2
12/22 : Ratio of two variances
H0 : 12/22 = 1
HA : 12/22 1

Hypothesis test results:

Hence,

p - Value = 0.2241

Option A is correct.

Answer - 3: p - Value = 0.7144

Option B is correct.

Ratio Num. DF Den. DF Sample Ratio F-Stat P-value 12/22 24 29 1.6044444 1.6044444 0.2241
