A carnival ride has cars that each hold 4 44 adult passengers. The weights of the passengers for this ride are normally distributed with a mean of 65 kg 65kg65, start text, k, g, end text and a standard deviation of 12 kg 12kg12, start text, k, g, end text. Assume that the weights of passengers are independent from each other. Let T = T=T, equals the total weight of 4 44 randomly selected adult passengers for this ride. Find the probability that the total weight exceeds 290 kg 290kg290, start text, k, g, end text. You may round your answer to two decimal places.

Aconcession manager at yankee stadium wants to know how temperature affects beer sales. she took a sample of 10 games and recorded the number of beers sold and the temperature in the middle of the game. temperature 80 68 78 79 87 74 86 92 77 84 number of beers 20533 1439 13829 21286 30985 17187 30240 87596 9610 28742 a. draw a scatter plot of the data. b. the manager estimates the regression equation to be: numberofbeers = −100, 678 + 1, 513 ∗ temperature draw this on your scatter plot. c. for one of the estimated points, indicate the residual with ei . d. for that same point, indicate what part of the variation is explained by the model with ˆyi − y¯.
