Explanation for Question 34 From the Math (Calc) Section on the 2018 May Sat
Question 34 says the number of people in millions who visited 2 amusement park a and amusement park beat in 2009 through 2013 3 are listed in the table below. What is the positive difference between the mean 4 number of people in millions who visited amusement park B and the mean number 5 of people in millions who visited amusement park a during those years. 6 So all we have to do is calculate the mean from both of these 7 datasets and then subtract a amusing park AEs mean from amusement park. 8 B's mean, so I'm going to start by finding the main for music park 9 B. So I'm going to add together all of these values in the chart, 10 and then divide by five. 11 And that is equal to 16.04. 12 Now I'm going to do the same exact thing for the data set on 13 the top for a music park, a and see what that gets divided 14 by five. And that's equal to 14.34. 15 And finally, I'm going to subtract the bottle mean from the top mean, 16 and I get 1.7, 17 which is already rounded to the nearest 10th. 18 And so that's our final answer.
