A sample mean, sample size, and sample standard deviation are provided below. Use the one-mean t-test to perform the required hypothesis test at the 1% significance level.
x=22 s=6 n=15 H0: M=24 Ha: M<24
The test statistic is t=
Homework Answers
The test statistic for a one sample t-test is as follows
= -1.2910
This is a one-tailed test, at 
= 0.01
We accept null hypothesis at 1% level of significance since
t > -2.6245
