Identify the null and alternative hypotheses in the following scenario: To determine if running shoes 1 have the same durability as running shoes 2, the mean durability, in miles, of the two competing running shoes is compared. Fourteen runners are randomly assigned to test each type of shoe. Both populations have normal distributions with known standard deviations. Select the correct answer below: H0:μ1≠μ2; Ha:μ1=μ2 H0:μ1=μ2; Ha:μ1≠μ2 H0:μ1≥μ2; Ha:μ1 μ2
