Canadian quarters are fair, aren't they? Suppose we want to test the claim that the probability of a Canadian quarter coming up heads is 50%.

QUESTION 9 (continuing...) Suppose we flip the coin n=100 times and observe x=44 heads. Calculate the appropriate test statistic for this sample. O a. 0.44 - 0.5 Z= - 1.20000 0.5 x 0.5 100 Ob. 0.44- 0.5 Z= = - 1.20873 0.44 X 0.56 100 O C. 0.44 -0.5 t = - 1.20000 0.5 x 0.5 100 O d. 0.44 -0.5 t=. 1.20873 0.44 x 0.56 100 QUESTION 10 (continuing...) Calculate the P-value. Round to four decimal places. QUESTION 11 (continuing...) What is the conclusion of our formal hypothesis test? a. We have sufficient evidence to accept the claim that the coin is fair. O b. We have insufficient evidence to accept the claim that the coin is fair. O c. We have sufficient evidence to reject the claim that the coin is fair. O d. We have insufficient evidence to reject the claim that the coin is fair
