QUESTION 1
Information for Questions 1-2: Data was collected by the Kaiser Foundation on Hieh School Fitness Levels. The following data represents the percent of High School Students who are
enough exercise. The data was collected from 42 of the 50 states. Eight states did not reply to the request for data.
% of H.S.Students Not Meeting Recommended Physical Activity Level
45
: :
48
54
Data for 42 States (8 States Dld Not Have Data)
51
57
60
Enter the information in the Dotplot into the StatList editor. Enter the values into L1 and the corresponding frequencies into L2. For example, the first enter into L1 is 45 and the corresponding entry
in L2 is 1 (because there is 1 dot in the 45 (percent) column in the Dotplot).
1. Using the information in L1 and L2, calculate the mean and standard deviation for this dataset.
O a. mean = 54.696 standard deviation - 3.15%6
O b. mean = 53.196 Standard deviation = 5.24%
C. mean = 53.196 Standard deviation - 5.196
O d. mean = 53.49% standard deviation = 4.3%
O e. mean - 5396 standard deviation - 6.29%
