Question

Assume that in this question adults spend an average of 104.1 minutes with a standard deviation of 26.4 minutes in the REM sleep stage each night and also that these times are normally distributed. What is the absolute least amount of time that an an adult could spend in REM sleep and still be in the 40% who spend the longest amount of time in REM sleep? The answer should have 1 decimal place.

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.
