we suspected an unusual distribution of blood groups in patients undergoing one type of surgical procedure. We know that the distribution for the population served by the hospital which performs this surgery is 44% group 0, 45% group A, 8% group B and 3% group AB. We can take a random sample of routine pre-operative blood and obtained the following results: O A B AB frequency 67 83 29 8 Test the claim that distribution of blood groups in these patients is different. Use a=0.1

c) Compute the test value: 01. X2= 17.04 O2. X2=12.04 03. X2= 14.04 d) Make the decision. 01. Reject the null hypothesis. O 2.Do not reject the null hypothesis. e) Summarize the results. 01. There is enough evidence to support the claim. 2.There is not enough evidence to support the claim.
