An amusement park keeps track of the percentage of individuals with season passes according to age category. An independent tourist company would like to show that this distribution of age category for individuals buying season passes is different from what the amusement park claims. The tourist company randomly sampled 200 individuals entering the park with a season pass and recorded the number of individuals within each age category. Age Category Child (under 13 years old) Teen (13 to 19 years old) Adult (20 to 55 years old) Senior (56 years old and over) Number of Individuals 56 86 44 14 The tourist company will use the data to test the amusement park’s claim, which is reflected in the following null hypothesis.

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.
