Answer 1

so it would be 65 per year

Answer 2

Answer:

37 is between 2 and 3 standard deviations of the mean.

Step-by-step explanation:

Given that the mean is 29 and the standard deviation is 3.6, then, 2 standard deviations of the mean is 29 + 2*3.6 = 36.2, and 3 standard deviations of the mean is 29 + 3*3.6 = 39.8. So, 37 is between 2 and 3 standard deviations of the mean.
