Question

Azli and Iman are both traveling for Batu Pahat to Melaka on daily basis. The
average travelling time for both them is 98.4 minutes with a standard deviation of
7.8 minutes and 110.7 minutes with standard derivation of 29.8 minutes
respectively. Assume that the traveling population are approximately normal
distributed and random samples of traveling time of Azli and Iman are 36 and 49
respectively.

i . Calculate the propabality that Iman’s travelling time is 13 mins more than
Azli’s travelling time

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.
