In a boys’ school, there are 40 students in grade 9. The weight of the students was measured. The mean weight of the students was 55 kg and the standard deviation was 2.5 kg. Peter’s weight was 64kg. Would his weight be considered an outlier, if the weight of the students were normally distributed? Explain your answer. In a boys' school, there are 40 students in grade 9.

Question

In a boys’ school, there are 40 students in grade 9. The weight of the students was measured. The mean weight of the students was 55 kg and the standard deviation was 2.5 kg. Peter’s weight was 64kg. Would his weight be considered an outlier, if the weight of the students were normally distributed? Explain your answer.

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.
