Use the Grouped Distribution method for the following exercise (see Self-Test 2-4 for detailed instructions), rounding each answer to the nearest whole number. Using the frequency distribution below (scores on a statistics exam taken by 80 students), determine:ion 1 of the preliminary test (scores on a statistics exam taken by 80 students), determine: 68 84 75 82 68 90 62 88 76 93 73 79 88 73 60 93 71 59 85 75 61 65 75 87 74 62 95...

Two placement exams are available that students can take to determine which math class they should begin with in their freshman year. It is believed that there is no difference in the mean scores that would be received for the two tests. To test this using a 0.05 level of significance, a randomly selected group of students took both tests and had their scores recorded. The following data were obtained: Student Test A Test B 1 78 82 2 86...
CSC888 has 4 people. Each person needs to take 3 tests. Create a 4-by-3 two-dimensional array to store the test scores. Ask the user to enter test scores one at a time to populate this array. Once the whole array is filled, do the following two things. (1) For each student, display her test scores and the average of the three tests. (2) For each test, display student scores and the average of the four students. The following shows a...
