To test this, he gathers information on 150 random sales and finds that 120 of those sales were made to women. The following is the setup for this hypothesis test: Họ : p = 0.75 Ha :p > 0.75 The p-value for this hypothesis test is 0.079. At the 1% significance level, choose the correct conclusion? Select the correct answer below: There is sufficient evidence to conclude that the proportion of sales he makes to women is more than 75%. There is NOT sufficient evidence to conclude that the proportion of sales he makes to women is more than 75%. There is sufficient evidence to conclude that the proportion of sales he makes to women is more than 50%. There is NOT sufficient evidence to conclude that the proportion of sales he makes to women is more than 50%. FEEDBACK へ e to search hp f12 f10 f4 f5 f6 10 144

Question

I got this answer already, which is B. I got this answer because the p-value is greater than the significance level. This means that "There is NOT sufficient evidence to conclude that the proportion of sales he makes to women is more than 75%." I would like some confirmation whether I am right or wrong.
