Question

Use excel and the function: =t.dist.rt(___,___) and multiply answer by 2 to find the p-value. Please find the p-value with 4 decimals

Find the p-value for the t-test of Ho: µ = 4 vs. Ha: µ > 4 where n = 11 and t = 2.646. Report 4 decimal places.

Answer #1

Please don't hesitate to give a "thumbs up" in case you're satisfied with the answer

The formula is :

=T.DIST.RT(2.646, 10) . The 10 is basically the degrees of freedom calculated by n-1 (11-1 = 10)
= .01224

Now, this is one sided. We multiply by 2 as asked in the question.

2*.01224 = .02448 or .0245

But since this is a one-sided test ( as Ha: Mu > 4) we have the p-value as .0122

Answer is .0122
