The student who scored a 79 on the test would like to 76 78 know if he is an outlier. If he is, then he wants to know if 82 84 Test scores 80 86 88 90 :- he is the only outlier. What do the data say? O No, he is not an outlier, but the student that scored an 89 is a high outlier. O No, there are not any outliers in this distribution.

C Choose the correct answer below. OA. The statement is true. B. The statement is false. The mode is the measure of central tendency most likely to be affected by an outlier. OC. The statement is false. The median is the measure of central tendency most likely to be affected by an outlier. OD. The statement is false. Outliers do not affect any measure of central tendency.

Joselyn hopes to receive a grade of B or better in her statistics class. Currently she has scored 75, 83, and 81 on her three in-class tests and also has a homework average of 88. Her professor calculates the class grade by finding the mean of five grades: three in-class tests, the homework average and the final exam. What is the minimum score Joselyn must earn on the final exam to have a class grade (mean) of 80? A. 67 B. 95 C. 70 D. 73
