Answer to Problem 5E

The value of p^1 , p^2 , q^1 and q^2 is 0.5, 0.44, 0.5 and 0.56, respectively.

Explanation of Solution

Given info:

X1=25 , n1=75 , X2=40 and n2=90 .

Calculation:

The value of p^1 is,

p^1=X1n1=2575=0.5

The value of q^1 is,

q^1=1p^1=10.5=0.5

The value of p^2 is,

p^2=X2n2=4090=0.44

The value of q^2 is,

q^2=1p^2=10.44=0.56

Thus, the value of p^1 , p^2 , q^1 and q^2 is 0.5, 0.44, 0.5 and 0.56, respectively.

Answer to Problem 5E

The value of p^1 , p^2 , q^1 and q^2 is 0.6, 0.4, 0.35 and 0.65, respectively.

Explanation of Solution

Given info:

X1=9 , n1=15 , X2=7 and n2=20 .

Calculation:

The value of p^1 is,

p^1=X1n1=915=0.6

The value of q^1 is,

q^1=1p^1=10.6=0.4

The value of p^2 is,

p^2=X2n2=720=0.35

The value of q^2 is,

q^2=1p^2=10.35=0.65

Thus, the value of p^1 , p^2 , q^1 and q^2 is 0.6, 0.4, 0.35 and 0.65, respectively.

Explanation of Solution

Given info:

X1=3 , n1=20 , X2=5 and n2=40 .

Calculation:

The value of p^1 is,

p^1=X1n1=320=0.15

The value of q^1 is,

q^1=1p^1=10.15=0.85

The value of p^2 is,

p^2=X2n2=540=0.125

The value of q^2 is,

q^2=1p^2=10.125=0.875

Thus, the value of p^1 , p^2 , q^1 and q^2 is 0.15, 0.85, 0.125 and 0.875, respectively.

Answer to Problem 5E

The value of p^1 , p^2 , q^1 and q^2 is 0.42, 0.58, 0.64 and 0.36, respectively.

Explanation of Solution

Given info:

X1=21 , n1=50 , X2=32 and n2=50 .

Calculation:

The value of p^1 is,

p^1=X1n1=2150=0.42

The value of q^1 is,

q^1=1p^1=10.42=0.58

The value of p^2 is,

p^2=X2n2=3250=0.64

The value of q^2 is,

q^2=1p^2=10.64=0.36

Thus, the value of p^1 , p^2 , q^1 and q^2 is 0.42, 0.58, 0.64 and 0.36, respectively.
