Question

Calculate and answer. Show complete solution.

The height of adolescent females in Canada is said to be normally distributed. Furthermore, the average height of a random sample of 30 Canadian adolescent females is found to be 74.39 inches, with a standard deviation of 5.24. Determine the standard error of the sample mean.

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.
