Question

If the sample mean = 50, population mean = 44, sample standard deviation = 6, and sample size = 9, what is the one sided t-score of the sample?

Answer 1

`t=3`

Explanation:

Given -

Population Mean `mu=44`
Sample Mean `barx=50`
Sample standard deviation `s=6`
Sample size `n=9`

Standard Error `=s/sqrtn=6/sqrt9=6/3=2`

`t=(barx-mu)/(SE)=(50-44)/2=6/2=3`

`t=3`
