Question 236504: A machine produces 9 inch latex gloves. A sample of 69 gloves is selected, and it is found that 45 are shorter than they should be. Find the 98% confidence interval on the proportion of all such gloves that are shorter than 9 inches. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! A machine produces 9 inch latex gloves. A sample of 69 gloves is selected, and it is found that 45 are shorter than they should be. Find the 98% confidence interval on the proportion of all such gloves that are shorter than 9 inches.
------------------------------------
p-hat = 45/69 = 0.65
E = 2.326*sqrt[0.65*0.35/69] = 0.133
----------------
98% C.I.: 0.65=0.134 < p < 0.65+0.134
