Carry out the 9 steps of hypothesis testing. 4. Last year the government made a claim that the average income of the American peonle was $33,950. However, a sample of 50 people taken recently showed an average income of $34,076 with a standard deviation of $324. Is the government's estimate different? Conduct a significance test to see if the true mean is different than the reported average. Use an a = 0.01. What's given? Ox= X = Sr = N = a = Steps to the hypothesis test: 1) State the null and alternative hypothesis: Ho: elas На: 2) Two-tailed or one tailed? 3) What is the a level? 4) Would you do a t test or z test? 5) Report the possible critical values for your test (Zarit or tarit). 6) Calculate the test statistic (Zobt or tobt). 7) Does the test statistics fall in the critical region? At which alpha level? 8) Would you fail to reject (accept) or reject the null hypothesis? At which Confidence level? ) 190 9) State Your conclusion.
