In 2013, the average age of a first-time mother (the mother's age on the day of her first child's birth) was 21.4 (Source: www.babycenter.com). The ages of a random sample of first-time mothers are to be used to decide whether this year's mean age of first-time mothers is more than it was in 2013. The null and alternate hypotheses for the hypothesis test are: H0: = 21.4 years H1: > 21.4 years, where is this year's mean age of all first-time mothers. Explain what each of the following would mean. a) a Type 1 error- b) a Type 2 error- c) a correct decision
