(a) 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.
