Based upon data from his AP United States History class, Mr. Unsworth determined that the relationship between a student's hours watching TV per week (x) and that student's score on the AP
(y) exam were negatively correlated. He determined that the equation of the best fit line is
y = -0.21x + 5.22. Based upon these results, predict a student's AP score (to the nearest whole
number) if he watches 12 hours of TV a week.

Analyze the data sets below. data set a 25,25,25,26,26,26,27,28,28,29,30,31 ,31,32,33,33,34,35,35,35 data set b 25,25,25,26,26,26,26,27,27,27,27,28 ,28,29,29,30,31,31,32,34 which of the following statement are true? select all that apply. a. data set a is relatively symmetric and data set b is skewed left. b. the means of the data sets are within 3 units from eachother. c. the data sets have the same standard deviation. d. the mean of data set a is 27.95 and the mean of data set b is 30. e. the data set b has a higher standard deviation than data set a. f. the mean and median of data set a are close in value.
