Why the correct answer is D? The distribution of the time it takes for different people to solve a certain crossword puzzle is skewed to the right, with a mean of 30 minutes and a standard deviation of 15 minutes. The distribution of z-scores for those times is (a) Normally distributed, with mean 30 and standard deviation 15. (b) skewed to the right, with mean 30 and standard deviation 15. (c) Normally distributed, with mean 0 and standard deviation 1. (d) skewed to the right, with mean 0 and standard deviation 1. (e) skewed to the right, but the mean and standard deviation cannot be determined without more information.
