Transcribed Image Text:In the US, 45.4% of all people have type O blood, 39.5% have type A blood, 11.8% have type B blood and
3.3% 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 3552 millionaires. What can be
concluded at the a = 0.01 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
1611
A
1418
В
417
АВ
106
b. What is the correct statistical test to use?
Select an answer V
c. What are the null and alternative hypotheses?
Ho:
Blood type and income are independent.
Blood type and income are dependent.
O The distribution of blood type for millionaires is not the same as it is for Americans in general.
O The distribution of blood type for millionaires is the same as it is for Americans in general.
Hị:
O Blood type and income are independent.
O 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.
Blood type and income are dependent.
d. The degrees of freedom = |
e. The test-statistic for this data =
(Please show your answer to three decimal places.)
f. The p-value for this sample =
(Please show your answer to four decimal places.)
g. The p-value is Select an answer
h. Based on this, we should Select an answer
i. Thus, the final conclusion is...
O There is insufficient evidence to conclude that the distribution of blood type for millionaires is
not the same as it is for Americans in general.
O There is sufficient evidence to conclude that the distribution of blood type for millionaires is
the same as it is for Americans in general.
O There is insufficient evidence to conclude that blood type and income are dependent.
There is sufficient evidence to conclude that blood type and income are dependent.
