According to government data, the probability that a woman between the ages of 25 and 29 was never married is 40%. a) In a random survey of 10 women in this age group, what is the mean and standard deviation of the number that never married? b) Suppose that in a random survey of 10 women in this age group, 6 women stated that they were never married. Use the answers to part (a) to determine if 6 was a usual or unusual number out of 10 women to say that they were never married (calculate the two standard deviation interval).
