Question

Let μ1 be the average height of sixth graders from California and μ2 be the average height of sixth graders from Texas. Assuming equal variances, conduct a right-tailed, independent t-test on the data. Select a correct set of null hypothesis H0 and alternative hypothesis Ha from the following: Group of answer choices

H0: μ1 = μ2 Ha: μ1 > μ2

H0: μ1 = μ2 Ha: μ1 < μ2

H0: μ1 ≠ μ2 Ha: μ1 = μ2

H0: μ1 = μ2 Ha: μ1 ≠ μ2

Answer 1

since the test is right tailed which means , we have > sign in the alternate hypothesis

correct option is:

H0: μ1 = μ2 Ha: μ1 > μ2
