Blood Types A medical researcher wishes to see if hospital patients in a large hospital have the same blood type distribution as those in the general population. The distribution for the general population is as follows: type A, 24%; type B, 28%; type O, 36%; and type AB=12%. He selects a random sample of 50 patients and finds the following: 14 have type A blood, 10 have type B, 23 have type O, and 3 have type AB blood. At α=0.01, can it be concluded that the distribution is the same as that of the general population? Use the critical value method with tables. H0: The blood type distribution is the same as the distribution of the general population. Claim or not? H1: The blood type distribution differs from the distribution of the general population: Claim or not? Find the critical value Compute the test value: X^2= Reject or Do not reject the null hypothesis Summarize: Is there or is there not enough evidence to reject the claim? Is there or is there not enough evidence to support the claim?

Question
Blood Types A medical researcher wishes to see if hospital patients in a large hospital have the same blood type distribution as those in the general population. The distribution for the general population is as follows: type A, 24%; type B, 28%; type O, 36%; and type AB=12%. He selects a random sample of 50 patients and finds the following: 14 have type A blood, 10 have type B, 23 have type O, and 3 have type AB blood.
At α=0.01, can it be concluded that the distribution is the same as that of the general population? Use the critical value method with tables.
- H0: The blood type distribution is the same as the distribution of the general population. Claim or not?
H1: The blood type distribution differs from the distribution of the general population: Claim or not? - Find the critical value
- Compute the test value: X^2=
- Reject or Do not reject the null hypothesis
- Summarize:
Is there or is there not enough evidence to reject the claim?
Is there or is there not enough evidence to support the claim?
