Just need some help with this.

One-sample procedures for proportions, like those for means, are used to analyze data from matched pairs designs. Here is an example. Each of 50 subjects tastes two unmarked cups of coffee and says which he or she prefers. One cup in each pair contains instant coffee; the other, fresh-brewed coffee. 33 of the subjects prefer the fresh~brewed coffee. Take p to be the proportion of the population who would prefer freshbrewed coffee in a blind tasting. (a) Test the claim that a majority of people prefer the taste of fresh-brewed coffee. 15 your result significant at the 5% level? What is your practical conclusion? 2 = P-value = Conclusion C There is significant evidence that a majority of people prefer the taste of freshbrewed coffee. C There is no evidence that a majority of people prefer the taste of fresh-brewed coffee. (b) Find a 80% condence interval for p. lower bound l upper bound l (c) When you do an experiment like this, in what order should you present the two cups of coffee to the subjects? C random order C instant coffee first C fresh-brewed coffee first
