35. A student working on a physics project investigated the relationship between the speed and the height of roller coasters. The student collected data on the maximum speed, in miles per hour, and the maximum height, in feet, for a random sample of 21 roller coasters, with the intent of testing the slope of the linear relationship between maximum speed and maximum height. However, based on the residual plot shown, the conditions for such a test might not be met. Residuals 0 50 l00150 200 250 300 Height Based on the residual plot, which condition appears to have been violated? (A) The errors are independent. (B) The sum of the residuals is 0. (C) The expected value of the errors is 0. (D) There is a linear relationship between the response variable and the explanatory variable. (E) The variance of the response variable is constant for all values of the explanatory variable
