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?

Question
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 = o.05 that more than two-thirds of the
%3D
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.
