Calculate the test statistic. T=___ (round to three decimal places as needed)

What is the range of values for the P value?
a. P-value > 0.20
b. 0.10 < P-value < 0.20
c. 0.025 < P-value < 0.10
d. 0.05 < P-value < 0.10
e. P-value < 0.01
f. 0.01 < P-value < 0.025

Identify the critical value ____, ____

State the final conclusion that addresses the original claim.

(Fail to reject, reject) H0. There is (sufficient, not sufficient) evidence to warrant rejection of the claim that the mean voltage is 120 volts.
