A sample of 10 men's GPA in college has sample mean 2.9, and a sample of 10 women's GPA has sample mean 3.1. We also know the GP
As of men and women have the same standard deviation 0.2. Calculate the p value.
1 answer:
Answer:
p-value = 0.02535
Step-by-step explanation:
From the information given:
For men:
The sample size n₁ = 10
The standard deviation s₁ = 0.2
The sample mean
2.9
For women:
The sample size n₂ = 10
The standard deviation s₂ = 0.2
The sample mean
3.1
Using the pooled variance;




= 0.08944
The z-test statistics is computed as:


z = - 2.236
The p-value = 2 × P(Z < -2.236)
From the z table;
p-value = 2 × (0.012675)
p-value = 0.02535

Answer:
e > 125
Step-by-step explanation:
Given
> 12.50
Multiply both sides by 10 to clear the fraction
e > 125
4[5(12*3)-2]-7
4[5(36)-2]-7
4[180-2]-7
4[178]-7
712-7= 705 :)
