Question
In the US, 43.4% of all people have type O blood, 39.8%
have type A blood, 11.9% have type B blood and 4.9% 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 3280 millionaires.
What can be concluded at the a = 0.05 significance level?
a. Complete the table by filling in the expected
frequencies. Round to the nearest whole number:
Frequencies of Blood Type
Outcome Frequency Expected Frequency

B
1425
1297
383
AB

b. What is the correct statistical test to use?
Goodness-of-Fit
c. What are the null and alternative hypotheses?
Ho:
Blood type and income are independent.
Blood type and income are dependent.
The distribution of blood type for millionaires
is not the same as it is for Americans in
general.
The distribution of blood type for millionaires
is the same as it is for Americans in general.
