Answer 1

To find the value two standard deviations above the mean for a sample, calculate the mean and standard deviation of the sample and add two times the standard deviation to the mean.

Step-by-step explanation:

To find the value two standard deviations above the mean for a given sample, we first need to calculate the mean and standard deviation of the sample. Then we can add two times the standard deviation to the mean to find the value.

In this case, the mean of the weight change sample is 2.5 pounds and the standard deviation is 10.2 pounds.

Adding two times the standard deviation to the mean, we get 2.5 + (2 * 10.2) = 22.9 pounds.
