Check Exercise 16-36 (Algo) (L016-6) Professor Bert Forman believes the students who complete his examinations in the shortest time receive the highest grades and those who take the longest to complete them receive the lowest grades. To verify his suspicion, he assigns a rank to the order of finish and then grades the examinations. The results are as follows: Order of Score (50 Order of Student Completion possible) Score (50 Student Completion Gromney possible) 1 44 Smythe 7 43 Bates 2 57 Arquette 8 57 MacDonald 3 49 Govito 9 47 Sosa 4 47 Gankowskt 10 44 Harris 42 Bonfigilo 11 54 Cribb 34 Matsui 12 40 2 Click here for the Excel Data File Convert the test scores to a rank and find the coefficient of rank correlation between the order of completion and the rank of the test score. At the 0.025 significance level, can Professor Forman conclude there is a positive association between the order of finish and the test scores? a. Calculate the coefficient of tank correlation (Round your answer to 3 decimal places) Coficient of rank correlation b. State the null and alternate hypotheses. Hs There is Ino correlation between the order of completion and the rank of the scores < Prev 8 of 8 !!! Next
b. State the null and alternate hypotheses Ho There is Hy. There is no correlation a positive correlation between the order of completion and the rank of the scores between the order of completion and the ranks of the scores c. State the decision rule. (Round your answer to 3 decimal places.) Reject Hot d. Calcualte the test statistic. (Round your answer to 3 decimal places.)
