Please use the following distribution table to get the answer!
5:
Let X shows the man weight and Y shows the woman weight. Here we have
1:
Let T= X+Y
Here T will have normal distribution with mean
and standard deviation
The z-score for T = 100 is
The required probability is
P(T > 100) = P(z > -1.27) = 1 - P(z <= -1.27) = 1- 0.102 = 0.8980
(2)
Let D =X-Y
Here D will have normal distribution with mean
and standard deviation
The z-score for D = 0 is
The required probability is
P(D < 0) = P(z < -0.85) = 0.1977
(3)
Let W =(3X /4)-Y
Here W will have normal distribution with mean
and standard deviation
The z-score for W = 0 is
The required probability is
