Variability in GMAT Scores.
Read Chapter 11 in your textbook. In 2016, the Graduate Management Admission
Council reported that the variance in GMAT scores was 14,660. At a recent summit, a
group of economics professors met to discuss the GMAT performance of undergraduate
students majoring in economics. Some expected the variability in GMAT scores achieved
by undergraduate economics students to be greater than the variability in GMAT scores
of the general population of GMAT takers. However, others took the opposite view. The
file EconGMAT contains GMAT scores for 51 randomly selected undergraduate
students majoring in economics.
By Sunday, Oct. 16 (11:55 pm PST), answer the following three questions A-C:
a. Compute the mean, variance, and standard deviation of the GMAT scores for the 51 randomly selected
undergraduate students majoring in economics.
b. Develop hypotheses to test whether the sample data indicate that the variance in GMAT scores for undergraduate
students majoring in economics differs from the general population of GMAT takers.
c. Use a = .05 to conduct the hypothesis test formulated in part (b). What is your conclusion?
