It appears that people who are mildly obese are less active than leaner people. One study looked at the average number of minutes per day that people spend standing or walking. Among mildly obese people, the mean number of minutes of daily activity (standing or walking) is approximately Normally distributed with 375 minutes and standard deviation 6565 minutes. The mean number of minutes of daily activity for lean people is approximately Normally distributed with 530 minutes and standard deviation 109 minutes. A researcher records the minutes of activity for an SRS of 55 mildly obese people and an SRS of 55 lean people. (a) What is the probability that the mean number of minutes of daily activity of the 55 mildly obese people exceeds 410 minutes? (Enter your answer rounded to four decimal places.)
