(a) Calculate the value of the test statistic used in this test.
Test statistic's value= 3.745
(b) Use your calculator to find the P-value of this test.
P-value= 0.001
(c) Use your calculator to find the critical value(s) used to test this claim at the 0.07 significance level. If
there are two critical values, then list them both with a comma between them.
Critical value(s) = 1.415, -1.415
(d) What is the correct conclusion of this hypothesis test at the 0.07 significance level?
