(1 point) A new cream that advertises that it can reduce wrinkles and improve skin was subject to a recent study. A sample of 59| women over the age of 50 used the new cream for 6 months. Of those 59| women, 38% of them reported skin improvement(as judged by a dermatologist). Is this evidence that the cream will improve the skin of more than 60l% of women over the age of 50? Test using a = 0.01). (a) Test statistic: 2 = (b) Critical Value: 2* = (c) The final conclusion is O A. We can reject the null hypothesis that p= 0.6ſ and accept that p > 0.6). That is, the cream can improve the skin of more than 60% of women over 50. OB. There is not sufficient evidence to reject the null hypothesis that p=0.6). That is, there is not sufficient evidence to reject that the cream can improve the skin of more than 60% of women over 50.
