In the US, 45.8% of all people have type O blood, 39.6% have type A blood, 10% have type B blood and
4.6% have type AB blood. A researcher wants to see if the distribution of blood type is different for
millionaires. The table below shows the results of a random sample of 3520 millionaires. What can be
concluded at the a = 0.10 significance level?
a. Complete the table by filling in the expected frequencies. Round to the nearest whole number:
