Question
Consider the following hypothesis test.
H0: u1 - u2 ≤ 0
Ha: u1 - u2 > 0
The following results are for two independent samples taken from the two populations.
Sample 1 | Sample 2 |
n 1 = 30 | n 2 = 50 |
x 1 = 25.7 | x 2 = 22.1 |
σ 1 = 5.6 | σ 2 = 7 |
a. What is the value of the test statistic (round to 2 decimals)?
b. What is the p-value (round to 4 decimals)? Use z-table. Use z-value rounded to 2 decimal places.
c. With = .05, what is your hypothesis testing conclusion?
p-value is H0
