- Lower limit: Your answer is incor Using the latest in medical technology, an orthopedic doctor has developed a new surgical procedure. He wants to estimate the difference between the mean recovery time of patients who have the new procedure and the mean recovery time of patients who have the standard procedure. The doctor studies a random sample of 11 patients who have the new procedure and a random sample of 10 patients who have the standard procedure. (These samples are chosen independently.) The doctor records each patient's recovery time (in days). The patients who had the new procedure have a sample mean recovery time of 367.2 with a sample variance of 1781.8. The patients who had the standard procedure have a sample mean recovery time of 392.5 with a sample variance of 122.1. Assume that the two populations of recovery times are approximately normally distributed. Let μ, be the population mean recovery time of patients who have the new procedure. Let μ₂ be the population mean…At home or in your community look for the least three(3) situations that could represent functions from identified situations write a sample problem and its corresponding function equationPrediction intervals are not sensitive to the normality assumption because Xn+1 is a future observation True False
