r the age of 50 used the new cream for 6 months. Of those 53 women, 44 of them reported skin improvement (as judged by a dermatologist). Is this evidence that the cream will improve the skin of more than 50% of women over the age of 50? Test using α= 0.05.(a) Test statistic: = _____(b) Critical Value = _____(c) The final conclusion is:A. There is not sufficient evidence to reject the null hypothesis that p = 0.5. That is, there is not sufficient evidence to reject that the cream can improve the skin of more than 50% of women over 50.B. We can reject the null hypothesis that p = 0.5 and accept that p > 0.5. That is, the cream can improve the skin of more than 50% of women over 50.
