Provided below are summary statistics for independent simple random samples from two populations. Use the
nonpooled t-test and the nonpooled t-interval procedure to conduct the required hypothesis test and obtain the specified
confidence interval.
x₁ = 8, S₁ = 4, n₁ =25, x₂ = 13, S₂ = 9, n₂ = 25
a. Two-tailed test, α = 0.01
a. What are the hypotheses for the t-test?
O A. Ho: H₁ = H2
Hai H₁ H₂
O C. Ho: H=H2
Hai #H2
Find the test statistic.
b. 99% confidence interval
t= (Round to three decimal places as needed.)
Find the critical values.
±ta/2= ± (Round to three decimal places as needed.)
OB. Ho: H₁2 H₂
Hai H₁ <H₂
O D. Ho: H₁ H2
Hai H1<H2
63.
