Suppose you have a data set that contains 100 integer values with a minimum of 54 and a maximum of 105. You have decided that there should be 7 classes since 7 is the smallest integer for k that satisfies 2k ≥ 100. Determine the limits of the first two classes by starting the first class with the minimum value.
choose the right answer:
54 to < 63
63 to < 72
54 to < 64
64 to < 74
54 to < 61
61 to < 68
54 to < 62
62 to < 70
Homework Answers
Number of classes = 7
Class width = (105 - 54)/7
= 7.28
8
First class is 54 to 54+8, that is, 54 to < 62
Second class = 62 to 62+8, that is 62 to < 70
Answer
54 to < 62
62 to < 70

Problem 4: Variables that may affect Grades The data set contains a random sample of STAT 250 Final Exam Scores out of 80 points. For each individual sampled, the time (in hours per week) that the student spent participating in a GMU club or sport and working for pay outside of GMU was recorded. Values of 0 indicate the students either does not participate in a club or sport or does not work a job for pay. The goal of...

West Battery Corp. has recently been receiving complaints from retailers that its 9-volt batteries are not lasting as long as other name brands. James West, head of the TOM program at West's Austin plant, believes there is no problem because his batteries have had an average life of 60 hours, about 10% longer than competitors' models. To raise the time above this level would require a new level of technology not available to West. Nevertheless, he is concerned enough to...
