c). Using ? = .01 would you ACCEPT or REJECT the null hypothesis (circle one) 3). An investigator wishes to estimate the proportion of students at a university who have traveled abroad. How large a sample should be taken if he wishes to be 98% confident that the estimation error is no more than .02. Use the fact that is thought that the proportion is in the region of 0.35. (also 99%, .03, .4 and 95%, .04, .2) n = __________ please work out I dont know how to get Z Solution Given a=0.02, |Z(0.01)|=2.33 (check standard normal table) So n=(Z/E)^2*p*(1-p) =(2.33/0.02)^2*0.35*(1-0.35) = 3087.687 Take n= 3088.
