The proportions of blood types O, A, B, and AB in the general population are known to 0.49, 0.38, 0.09, and 0.04 respectively. A research team investigating a small isolated community found the following frequencies of blood types.

Do the proportions in this community differ significantly from the general population?

(a) State the hypotheses, H0 and HA.

(b) Conduct a univariate Chi-Square Goodness of Fit test claim at a 0.05 significance level to compare the proportions of blood types in the community to the proportions in the general population. What is the value of the X 2 test statistic? How many degrees of freedom?

(c) Interpret the results.
