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. QUESTION 4What is the P-value for the test? (You may use the websites https://goodcalculators.com/chi-square-calculator/, https://www.statdistributions.com/chisquare/, Excel, or a graphing calculator.)
