19. A study was conducted to examine the length of time needed for the completion of an assigmnent for a biostatistics course. Two samples of 50 male students and 50 female students were used in this experiment. These students were requested to solve the same assignment consisting of 3 problems. and the time (in minutes) needed for the completion of the assignment was recorded for each person. Below is the summary of the data: Male Female HI = 50 712 = 5(1 131 : 40 1E2 : 38 5% = 18 s; = 14 Based on this data, is there a signicant difference in the time needed for the com- pletion of an assignment between the male and female populations of students? Use a test of level a = 0.02. Report the pvalue and the conclusion of the test. (A) pwalne=0.0062. There is not a signicant difference in the time needed for the completion of an assignment between the male and female populations. (B) pvalue=.062. There is a signicant difference in the time needed for the completion of an assignment between the male and female populations. 6 (C) pvalue=0.0124. There is a signicant difference in the time needed for the completion of an assignment between the male and female populations. (D) p\ alue=.()124. There is a not signicant difference in the time needed for the completion of an assignment between the male and female populations. (E) pvaliie:U.0248. There is a not signicant difference in the time needed for the completion of an assignment between the male and female populations
