Transcribed Image Text:Provided below are summary statistics for independent simple random samples from two populations. Use the
pooled t-test and the pooled t-interval procedure to conduct the required hypothesis test and obtain the specified
confidence interval.
x₁ = 11, S₁ = 2.5, n₁ = 15, x₂ = 14, s₂ = 2.2, n₂ = 15
a. Two-tailed test, α = 0.10
b. 90% confidence interval
Next, compute the test statistic.
t= (Round to three decimal places as needed.)
Now determine the critical values.
±ta/2= ±
What is the conclusion of the hypothesis test?
(Round to three decimal places as needed.)
Since the test statistic
in the rejection region,
to.
C...
b. The 90% confidence interval is from
