Question

Suppose that people heights (in centimeters) are normally distributed, with a mean of 170 and a standard deviation of 5. A.) What is the probability that a person’s height is between 170 and 182 cm tall? Round answer to four decimal places B.) if we find the heights of 50 people, how many would you expect to be between 170 and 182cm tall? Round answer to the nearest whole number

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.
