(1 point) A new cream that advertises that it can reduce wrinkles and improve skin was subject to a recent study. A sample of 69 women over the age of 50 used the new cream for 6 months. Of those 69 women, 59 of them reported skin improvement(as judged by a dermatologist). Is this evidence that the cream will improve the skin of more than 60% of women over the age of 50? Test using a = 0.01 (a) Test statistic: z = (b) Critical Value: z+ = (c) The final conclusion is O A. There is not sufficient evidence to reject the null hypothesis thatp= 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. OB. We can reject the null hypothesis that p women over 50. 0.6 and accept that p > 0.6. That is, the cream can improve the skin of more than 60% of

Of those 69 women, 59 of them reported skin improvement(as judged by a dermatologist). Is this evidence that the cream will improve the skin of more than 60% of women over the age of 50? Test using a =0.01. (a) Test statistic: z = (b) Critical Value: z* = (c) The final conclusion is OA. There is not sufficient evidence to reject the null hypothesis thatp= 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. OB. We can reject the null hypothesis that p 0.6 and accept that p > 0.6. That is, the cream can improve the skin of more than 60% of women over 50.
