QUESTION 1What are the expected frequencies? Type the values into the given boxes for blood type OQUESTION 2AB, and AB According to the Stanford School of Medicine Blood Center, blood type for Americans is distributed as follows:TypeOABABPercentage 44%42%10%4%A random sample of 200 Americans is selected and the blood type is recorded for each. The data is summarized in the table below.TypeOABABFrequency 84801917A Chi-square Goodness of Fit Test is conducted to test the hypotheses:Ho: The observed frequencies are consistent with the stated percentages. (The distribution of blood type appears to be correct.)HA: The observed frequencies are inconsistent with the stated percentages. (At least one of the stated percentages is incorrect.)Answer the questions given below.
