1. YOU MAY NEED TO USE STATCRUNCH TO ANSWER THIS QUESTION.You wish to test the following claim (HaHa) at a significance levelof α=0.001α=0.001. For the context of thisproblem, μd=μ2−μ1μd=μ2-μ1 where the first data setrepresents a pre-test and the second data set represents apost-test. Ho:μd=0Ho:μd=0 Ha:μd>0Ha:μd>0You believe the population of difference scores is normallydistributed, but you do not know the standard deviation. You obtainpre-test and post-test samples for n=11n=11 subjects. Theaverage difference (post - pre) is ¯d=20.2d¯=20.2 with astandard deviation of the differences of sd=23.1sd=23.1.What is the critical value for this test? (Report answer accurateto two decimal places.)critical value = What is the test statistic for this sample? (Report answer accurateto two decimal places.)test statistic = The test statistic is...
This test statistic leads to a decision to...
As such, the final conclusion is that...
2.
You are performing a left-tailed matched-pairs test with 21 pairs of data. If a = .01, find the critical value, to two decimal places.
