A) The distribution of will be approximately normal with mean 20 and standard deviation 7.
B) The distribution of will be approximately normal with mean 20 and standard deviation 1.
C) The mean and standard deviation of will be 20 and 7, but the sampling distribution of will not be approximately normal.
D) The mean and standard deviation of will be 20 and 1, but the sampling distribution of will not be approximately normal.
E) will have a standard normal distribution.
