Question

At a large corporation, 25% of a random sample of male employees have an average salary of $75,000 or higher. A random sample of female employees shows that 20% have an average salary of $75,000 or higher. A representative for the Equal Pay Act wants to determine whether there is evidence of a difference in salaries between males and females. What would she write as the null and alternative hypotheses for this situation? (2 points)

H0:p1 − p2 = 0 and Ha:p1 − p2 > 0

H0:p1 − p2 = 0 and Ha:p1 − p2 < 0

H0:p1 − p2 = 0 and Ha:p1 − p2 ≠ 0

H0:p1 − p2 > 0 and Ha:p1 − p2 = 0

H0:p1 − p2 > 0 and Ha:p1 − p2 ≠ 0

Answer 1

Answer:

H0:p1 − p2 = 0 and Ha:p1 − p2 ≠ 0

Step-by-step explanation:

H0:p1 − p2 = 0 and Ha:p1 − p2 ≠ 0

The null hypothesis is that there is no difference between the salaries between males and females

against the claim

The alternate hypothesis that there is a difference between the salaries between males and females.

The null hypothesis is reverse of the alternate hypothesis or the claim.

The claim can be set as the alternate hypothesis or the null hypothesis .
