The table below shows sample and population statistics for height.
Sample
Size 49
Mean 65
Standard Dev. 2.0
Population
Size 1000
mean 64
Standard dev. 1.0
Are the sample height and population height significantly different? (p=0.05)
How different are they?
Is the difference significant at p=0.01
Homework Answers
Answer #1
Since p-value is less than 0.05 so the sample height and population height are significantly different at 0.05 significance level.
Since p-value is less than 0.01 so the sample height and population height are significantly different at 0.01 significance level.
