Question

A supervisor at a call center reviewed 500 calls taken by four employees and rated the employees' performance on each call on a scale from 1 star to 4 stars. The ratings for each employee are shown in the table above. According to the table, to the nearest whole percent, what percent of Employee A's calls received a rating of 1 star?

College Board · Accepted Answer

The correct answer is B. Choice B is correct. The percent of Employee A's calls that received a rating of 1 star is the number of Employee A's 1 -star calls divided by the total number of Employee A's calls. This quotient, (16)/(145) , is approximately equal to 0.1103 , or 11.03% . To the nearest whole percent, this is 11% .
