Your neighborhood gym tracked how many days each of its members worked out over the past week. Let G = the number of days per week a member worked out.
A 2-column table with 8 rows. Column 1 is labeled number of days with entries 0, 1, 2, 3, 4, 5, 6, 7. Column 2 is labeled probability with entries 0.49, 0.12, 0.13, 0.15, 0.06, 0.02, 0.02, 0.01.
Interpret the standard deviation of G.
A. The mean number of days a member worked out would typically be about 1.6764 from the expected number of days.
B. The mean number of days a member worked out would typically be about 2.2913 from the expected number of days.
C. The number of days a member worked out would typically be about 1.6764 from the expected number of days.
D. The number of days a member worked out would typically be about 1.6764 from the mean about 68% of the time
The correct answer is C on edge.
