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 367367 minutes and standard deviation 6464 minutes. The mean number of minutes of daily activity for lean people is approximately Normally distributed with 525525 minutes and standard deviation 110110 minutes. A researcher records the minutes of activity for an SRS of 88 mildly obese people and an SRS of 88 lean people.

(a) What is the probability that the mean number of minutes of daily activity of the 88 mildly obese people exceeds 400400 minutes? (Enter your answer rounded to four decimal places.)

(b) What is the probability that the mean number of minutes of daily activity of the 88 lean people exceeds 400400 minutes? (Enter your answer rounded to four decimal places.)

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 367 minutes and standard deviation 64 minutes. The
mean number of minutes of daily activity for lean people is approximately Normally distributed with 525 minutes and
standard deviation 110 minutes. A researcher records the minutes of activity for an SRS of 8 mildly obese people and an SRS
of 8 lean people.
(a) What is the probability that the mean number of minutes of daily activity of the 8 mildly obese people exceeds 400

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
