Question

The height of waste bin manufactured by a factory for a garden have a normal distribution with mean as 1.25 m and standard deviation of 10 cm. How many percentage of waste bins manufactured were

a) More than 130 cm

b) Less than 115 cm

c) From 122 cm to 128 cm

d) Between 118 cm and 132 cm

e) At least 120 cm

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.
