(c) The following histogram summarizes the 65 residuals. The figure presents a histogram. The horizontal axis is labeled Residual, and the numbers negative 20 through 20, in increments of 10, are indicated. The vertical axis is labeled Frequency, and the numbers 0 through 25, in increments of 5, are indicated. The data represented by the bars are as follows. Note that all values are approximate. Residual, negative 20. Frequency, 0. Residual, negative 15. Frequency, 1. Residual, negative 10. Frequency, 5. Residual, negative 5. Frequency, 15. Residual, 0. Frequency, 20. Residual, 5. Frequency, 18. Residual, 10. Frequency, 5. Residual, 15. Frequency, 1. Residual, 20. Frequency, 0.
Assume that the distribution of residuals is approximately normal with mean 0cm and standard deviation 5.9cm. What percent of the residuals are greater than 8cm? Justify your answer.
