You want to evaluate the relationship between attendance for classes and performance on final exams among university students at Western. To save time, you decided to collect data from 10 students in a first-year statistics class and asked about their attendance and their scores on the final exam for the statistics course. Assume that there were 50 students in this statistics class, and each one is labeled 01 through 50. a) [1 point] What is the population for this survey? b) [1 point] What is the sample? c) [2 points] Starting on line 106 of Table B, who are the 10 students you would select for the survey? d) [3 points] Since you only surveyed students from a first-year class, can you identify a confounding variable in this situation? How could you change your study to address this issue
