Question

The one-sample -statistic for a test of Ho: u = 42 versus H1: /i < 42 based on n = 15 observations has the value 1=1.757, whe

Answer 1

Answer #1

Test Statistic :-

t = - 1.757

Looking for the value t = 1.757 in t table across n - 1 = 15 - 1 = 14 degree of freedom for one tailed test

Value t = 1.757 lies between the values T.JJU 1.345 1.761 in t table

Respective P values for one tailed is 0.10 0.05

0.05 < P value of the test < 0.10

Using excel we can calculate exact P value = 0.0504

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...
