the Spotted Manumar has 4 different blood types:  M, N, P and MN. Type MN is uncommon: 0.10 of them have this type. the rest 0.90 of the animals are equally split among the 3 other types. On another continent, there is another sub-species of the Manumar.  The Furry Manumar also has the same 4 blood types and the researchers wonder if the proportions of bloodtypes matches that of the Spotted ones. Of 200 sampled Furry Manumars, 35 had bloodtype MN and the rest were evenly split. The test statistic for this Goodness of Fit Test can be computed to be 12.5.    Determine the numeric portion of this number attributable to just the MN blood type.

2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.
