QUESTION 10 there ve 4observat ons then how many degrees of freedom are there for the t dstnbutondor a sample mean? 45 QUESTION 11 Suppose you agoing to test the null hypothesis that -30 Ho 30. You are gong to usea t test and your sample has 56 obser tatistic? Or in simpler language, how many degrees of freedom are there? acond. How many degrees cf freedom are there for the distribution of your test QUESTION 12 Suppose you are going to conduct a two tall test concerning the population mean. Suppose that you do not know what the population standard deviation is and that you have a sample of 55 observations. if you are going to conduct thio test at the .01 level of Sirificance what is the critical value? Be ure to enter positive number and answer to four decmal places. 23961 QUESTION 13 You are going to conduct a test of the null hypothesis, HoS.True or false: this is a right tail test and the rejection region is on the right True False QUESTION 14 You are going to conduct a test of the null hypothesis, HoiMs-2S0. True or false: this is a left talil test and the rejection region is on the left True False

Explanation / Answer

Given:

10) Number of observations are 49

So degree of freedom for the t distribution is (n-1) i.e. 48

11)mean=30 and sample has observations are 56

So degree of freedom of t -test is (n-1)=55
