Question 1 n The response to this question is the direct application of Property Number 2 which says that when a large number of samples of size N each are drawn from a normal population and a sampling distribution is constructed, then the mean of that sampling distribution is the population mean. Since the mean in the population is 50 ice cream cones, the mean of the sampling distribution is 50 also.

Question 2 n This question is the direct application of property number 3. As per property number 3, the standard deviation of the sampling distribution is lower than the sampling distribution of the population. Since the standard deviation of the population is 1.5, you expect the standard deviation of the sampling distribution to be lower than 1.5.
