Question

Instructor gender. In the study described in Exercise 17.33, researchers also examined the effect of the sex of an instructor on performance of students on a quiz. The researchers found no evidence of a difference in scores. (P = 0.24). The P-value refers to a null hypothesis of “no difference” in quiz scores measured on classes taught by male and female instructors. Explain clearly why this value provides no evidence of a difference.

Answer 1

Ans:

H₀ :There is no difference in quiz scores measured on classes taught by male and female instructors.

H₁: There exists a difference in quiz scores measured on classes taught by male and female instructors.

Given that

P=0.24

We compare p-value with significance level alpha=0.01 or 0.05 or 0.1 etc. as p-value is greater than alpha,we fail to reject the null hypothesis.There is not sufficient evidence to conclude that there exists a difference in quiz scores measured on classes taught by male and female instructors
