(Included are page 1 and 2 of the standard normal distribution table.)
According to eMarketer, adults in the United States spend an average of 92 minutes per day on social media platforms Facebook, Snapchat, and Instagram in 2017. Assume that minutes per day on these platforms follow a normal distribution with a standard deviation of 28.

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.
