19.16 Test the null hypothesis at the .01 level of significance that the distribution of blood types for college students complies with the proportions described in the blood bank bulletin, namely, .44 for 0, .41 for A, .10 for B, and .05 for AB. Now, however, assume that the results are available for a random sample of only 60 students. The results are as follows: 27 for 0, 26 for A, 4 for B, and 3 for AB.

Create a sufficiently large expected frequency by combining B and AB blood types.

What type test should be performed to solve for this?
