An amusement park employee records the ages of the people who ride the new roller coaster during a fifteen-minute period. Ages of riders: 42, 14, 19, 30, 49, 48, 16, 24, 38, 53, 24, 15, 18, 20, 25, 11, 18, 49, 54, 20, 17, 26, 37, 15, 28. Complete the frequency table. Then select the correct histogram of the data. Interval Frequency 10−19 20−29 30−39 40−49 50−59 A g617049a B g617049b C g617049c D g617049d

A) 0.5(2) + 80 = 81

B) 83

C) f(4) = 0.5(4) + 80 = 82

g(x) = 2x + 79

Slope: (83-81)/(2-1) = 2

y = 2x + c

When x = 1, y = 81

81 = 2 + c

c = 79

g(x) = 2x + 79

g(4) = 2(4) + 79 = 87

Since 87 > 82,

Science has a higher average after 4 tests
