In a sample of 50 men, 44 said that they had less leisure time today than they had 10 years ago. In a sample of 50 women, 48 women said that they had less leisure time than they had 10 years ago. At α=0.10 is there a difference in the proportions?

Group of answer choices

A.P value=0.1404; fail to reject H0

B.P value=0.1385; fail to reject H0

C.P value=0.1193; fail to reject H0

D.P value=0.1221; fail to reject H0

Answer #1

Test and CI for Two Proportions

Method

p₁: proportion where Sample 1 = Event
p₂: proportion where Sample 2 = Event
Difference: p₁ - p₂

Descriptive Statistics

Sample N Event Sample p
Sample 1 50 44 0.880000
Sample 2 50 48 0.960000

Estimation for Difference

Difference 95% CI for
Difference
-0.08 (-0.185183, 0.025183)

CI based on normal approximation

Test

Null hypothesis H₀: p₁ - p₂ = 0
Alternative hypothesis H₁: p₁ - p₂ ≠ 0
Method Z-Value P-Value
Normal approximation -1.47 0.1404

The pooled estimate of the proportion (0.92) is used for the tests.
The normal approximation may be inaccurate for small samples.

Option:- .P value=0.1404; fail to reject H0
