Answer to Problem T2.8SPT

Skewed to the right with mean 0 and SD 1

Explanation of Solution

The population distribution would be skewed to the right of a mean of 30 minutes and standard deviation of 15 minutes

The shape of the distribution of the z-scores is every time the same as the shape of the population distribution, which means that the z-scores have a skewed to the right distribution.

However, the z-score every time have mean zero and standard deviation is one, because the z-scores are the standardized version of the data values.

Hence, the correct option is (d)
