P value for claim P < 0.25 is 0.0625 ( left tailed test )
P value for claim P > 0.25 is ( 1 - 0.0625 ) = 0.9375 ( right tailed test )
Option C is correct.

In a test of hypotheses Ho: M = 456 versus H1:4< 456, the rejection region is the interval (-00, -1.796], the value of the sample mean computed from a sample of size 12 is x = 453, and the value of the test statistic is t = -2.598. The correct decision and justification are: O Reject Ho because 453 is less than 456 O Reject Ho because -2.598 lies in the rejection region O Do not reject Ho because -2.598...

How do you solve for the P-value?
In a hypothesis test with hypotheses Ho : j < 54 and H1 :u > 54, a random sample of 24 elements selected from the population produced a mean of 59.0 and a standard deviation of 14.0. The test is to be made at the 2.5% significance level. Assume the population is normally distributed. What is the critical value of t? 1.96 02.064 • 2.069 -2.069 What is the value of the test...
