Blood Types A medical researcher wishes to see if hospital patients in a large hospital have the same blood type distribution as those in the general population. The distribution for the general population is as follows; type A, 20%; type B, 28%; type O, 36%; and type AB= 16%. He selects a random sample of 50 patients and finds the following: 12 have type O, and 6 have type AB blood.

At a =0.10, can it be concluded that the distribution is the same as that of the general population?
