Reference no: EM1385951

The GMAT scores from a sample of 50 applicants to an MBA program indicate that none of the applicants scored below 450. A frequency distribution was formed by choosing class intervals 450 to 499, 500 to 549, and so on, with the last class having an interval from 700 to 749. Two applicants scored in the interval 450 to 499, and 16 applicants scored in the interval 500 to 549.

a. What percentage of applicants scored below 500?

b. What percentage of applicants scored between 500 and 549?

c. What percentage of applicants scored below 550?

d. What percentage of applicants scored below 750?
