293 pairs of swedish twins were studied THey consisted of 56

293 pairs of swedish twins were studied. THey consisted of 56 male -male pairs, 72 female-male pairs, and 65 female-female pairs. It is believed that a twin is equally likely to be female or male and that the sexes are determined independently. If this is the case then P(MM)=.25 P(FM)= .50 P(FF)=.25. Are the data consistent whith this belief? Perform the appropriate test of hypothesis using the .05 level of significance.

Iknow how to compute this by hand, but I do not know how to do it on minitab, specifically how to find the p-value on minitab
