The Sample Standard Deviations and Sample Sizes Are Given for Independent

question 86

Multiple Choice

The sample standard deviations and sample sizes are given for independent simple random samples from twopopulations. Use the two-standard-deviations F-test to conduct the required hypothesis test.
- $\mathrm { s } _ { 1 } = 5.85 , \mathrm { n } _ { 1 } = 31 , \mathrm {~s} _ { 2 } = 5.01 , \mathrm { n } _ { 2 } = 25$ ; two-tailed test, $\alpha = 0.10$

• A)Test statistic: \(\mathrm { F } = 1.17\). Critical values \(= 0.515,1.94\). Reject \(\mathrm { H } _ { 0 }\).
• B) Test statistic: \(\mathrm { F } = 1.36\). Critical values \(= 0.515,1.94\). Do not reject \(\mathrm { H } _ { 0 }\).
• C) Test statistic: \(\mathrm { F } = 1.17\). Critical values \(= 0.529,1.94\). Do not reject \(\mathrm { H } _ { 0 }\).
• D) Test statistic: \(\mathrm { F } = 1.36\). Critical values \(= 0.529,1.94\). Do not reject \(\mathrm { H } _ { 0 }\).
