Concept explainers
a)
To find the cutoff values for the highest 10% of the weights.
a)
Answer to Problem 39E
The cutoff values for the highest 10% of the weight 1259.52
Explanation of Solution
Given:
Formula:
P(Z > z) = 0.10
P(Z< z) = 1-0.10 = 0.90
z = 1.28
Using formula,
Hence, the cutoff values for the highest 10% of the weight 1259.52
b)
To find the cutoff values for the lowest20% of the weights.
b)
Answer to Problem 39E
The cutoff values for the lowest 20% of the weight 1259.52
Explanation of Solution
Given:
Formula:
P(Z < z) = 0.20
z = -0.84
Using formula,
Hence, the cutoff values for the lowest 20% of the weight 1081.44
c)
To find the cutoff values for the middle40% of the weights.
c)
Answer to Problem 39E
The cutoff values for the middle 40% of the weight between 1195.68 and 1108.32.
Explanation of Solution
Given:
Formula:
P(-z
z =
Using formula,
Hence, cutoff values for the middle 40% of the weight between 1195.68 and 1108.32.
