Chapter 8.2, Problem 8.9LM
Independent random samples of n1 = 233 and n2 = 312 are selected from two populations and used to test the hypothesis H0 : (μ1 – μ2) = 0 against the alternative H0 : (μ1 – μ2) ≠ 0 .
- a. The two-tailed p-value of the test is .1150. Interpret this result.
- b. If the alternative hypothesis had been Ha : (μ1 – μ2) = 0 , how would the p-value change? Interpret the p-value for this one-tailed test

The NAEP considers that a national average of 283 is an acceptable performance. Using α = .05, run a two-tail t-test for one sample to test Ho: µ=283 for the 2019 scores. Report the t-obt, df, and p-values.
Would you reject the null hypothesis that the 2019 scores come from a population with average 283? If this is the case, does it come from a population from larger or smaller average?
You do a hypothesis test of H0: μ = 5 vs Ha: μ ≠ 5 at significance level 0.05.
You collect a random sample and find your test statistic z = 2.10
What is the p value equal to?
a.

c.

d.
0.0179
e.
