7.20 A one-sample t test. The one-sample t statistic for testing Ho: μ = 8 Ha: μ > 8 from a sample of n = 22 observations has the value t = 2.24. (a) What are the degrees of freedom for this statistic? (b) Give the two critical values t* from Table D that bracket t. (c) Between what two values does the P-value of the test fall? (d) Is the value t = 2.24 significant at the 5% level? Is it significant at the 1% level? (e) If you have software available, find the exact P-value.

Question

I just need help with C-E

If its helpful for A) I got 21 degrees of freedom and B) I got [-1.721, 1.721]

7.20 A one-sample t test. The one-sample t statistic for
testing
Ho: μ = 8
Ha: μ > 8
from a sample of n = 22 observations has the value
t = 2.24.
(a) What are the degrees of freedom for this statistic?
(b) Give the two critical values t* from Table D that
bracket t.
(c) Between what two values does the P-value of the
test fall?
(d) Is the value t = 2.24 significant at the 5% level? Is it
significant at the 1% level?
(e) If you have software available, find the exact P-value.
