1.)What, me marry? In the United States, 20% of adults ages 25 and older have never been married, more than double the figure recorded for 1960. Select a random sample of 50 U.S. adults ages 25 and older and let Y = the number of individuals in the sample who have never married.
a) Calculate the mean and standard deviation of the sampling distribution of X.
b) Interpret the standard deviation from question 1
c) Would it be appropriate to use a normal distribution to model the sampling distribution of Y = the number of individuals in the sample who have never married? Justify your answer.
