14. Students in a statistics class would like to investigate if more than two-thirds of the Earth is water. To answer this question, students tossed an inflatable globe back and forth. After each catch, the
student recorded whether the tip of their pointer finger of their right hand was on water or land. In
50 tosses, their finger was on water 38 times. Assuming all conditions for inference are met, do the
data provide convincing statistical evidence at the significance level of a = 0.05 that more than two-
thirds of the Earth is water?
(A) Yes, because the p-value of 0.76 is greater than the significance level of 0.05.
(B) Yes, because the p-value of 0.08 is greater than the significance level of 0.05.
(C) Yes, because the p-value of 0.05 is less than the significance level of 0.08.
(D) No, because the p-value of 0.08 is greater than the significance level of 0.05.
(E) No, because the p-value of 0.03 is less than the significance level of 0.05.
