Question: "Suppose 63 of 105 randomly selected shoppers believe that "Made in the USA" means 100% of labor and materials are from the United States. Let p represent the true proportion of consumers who believe "Made in the USA" means 100% of labor and materials are from the United States. Complete parts a through e."

Please help me solve the parts to this question. If you can explain your steps too so I can learn how to do it I would appreciate it. Thanks!

HERE IS THE DROP DOWN OPTIONS FOR PART 'D':

Explanation / Answer

1) point estimate = p1 = x/n = 63/105 = .6 2) F 3) z = (p1 - Ho) / ((Ho*(1-Ho)/n)^0.5) = (0.6-0.7)/((0.7*0.3/105)^.05) = -2.236 = -2.24(round off) Ho = hypothesized proportion = .7 p1 = sample proportion = .6 4) z< -zalpha/2 or z >zalpha/2 critical value = 2.58, the critical z value corresponding to an upper probablity of 1-.005 5) C
