Explanation / Answer
H0: There are no population mean differences.
H1: At least one of the population mean differs.
Level of significance is .05
Test Statistics is 14.366
p-value is .000
Here the p-value is less than the level of significance (.05<.000); the null hypothesis can be rejected at 5% level of significance.
There is sufficient evidence to conclude that there is a difference among the prep program procedure students with the GRE results.
We find the minimum value for procedure 1 is 720 which is among all the procedure and the lower bound of the confidence interval is 738.0461, this is also highest among all the lower bound of the confidence interval.
The program 1 has the best GRE results.
