The table shows the number of grade 7 and grade 8 students on the student council at Jeremy’s school. Grade Levels of Student Council Members Number of Students Grade 7 17 Grade 8 34 Every day, two student council members are randomly chosen to read the morning announcements. Students cannot be chosen more than once to read the announcements. Jeremy designed a simulation for the selection of the students and gathered data to predict the probability that a seventh grade student will be chosen. In Jeremy’s simulation, he rolls two number cubes in each of 40 trials. In each trial, a cube landing on 1 or 2 represents a student in grade 7 being selected, and a cube landing on 3, 4, 5, or 6 represents a student in grade 8. Which statement best describes the flaw in Jeremy’s model? The number of sides on a cube does not match the number of grade levels. The number of sides on a cube is not a factor of the total number of students. The number of outcomes representing each grade level does not change after the first student is chosen. The number of outcomes representing a student in grade 7 is not the same as the number representing a student in grade 8.

If your score on your next statistics test is converted to a z score, which of these z scores would you prefer: minus2.00, minus1.00, 0, 1.00, 2.00? why? a. the z score of 2.00 is most preferable because it is 2.00 standard deviations above the mean and would correspond to the highest of the five different possible test scores. b. the z score of 0 is most preferable because it corresponds to a test score equal to the mean. c. the z score of minus2.00 is most preferable because it is 2.00 standard deviations below the mean and would correspond to the highest of the five different possible test scores. d. the z score of minus1.00 is most preferable because it is 1.00 standard deviation below the mean and would correspond to an above average
