Let’s talk about grades. Below is a collection of grades randomly selected from the students taking a statistics final exam administered to all students taking statistics at one college in one particular year. 69 70 70 72 73 73 76 77 77 7878 79 80 80 8081 82 82 83 8488 89 92 93 94 1. The 25 student scores above would represent... A.a sample statistic B.a parameter C.a census D.a population E.a sample 2.The professor wants to analyze the results of these grades. Find the median grade for the students. 3.Assume that the distribution is approximately normal with a mean and standard deviation of 80 and 7 respectively. What is the probability that a student would score higher than a 90 on the final? 4.
