Kareem is a demographer studying a city that has undergone recent changes. He claims that the mean household size in the city is now greater than Espanol 2.2 people. For a random sample of 23 households in the city, the households had a sample mean size of 2.4 people with a sample standard deviation of 0.9 people. Assume that the population of household sizes in the city is approximately normally distributed. Complete the parts below to perform a hypothesis test to see if there is enough evidence, at the 0.05 level of significance, to support that u, the mean household size in the city, is greater than 2.2 people. S (a) State the null hypothesis Ho and the alternative hypothesis H, that you would use for the test. OO Ho: H: 020 0-0 020 M X ? (b) Perform a hypothesis test. The test statistic has a f distribution (so the test is a "f test"). Here is some other information to help you with your test. . to.os is the value that cuts off an area of 0.05 in the right tail. 1 - x . The value of the test statistic is given by ? = S Student's t Distribution 04- Step 1: Enter the number of degrees of freedom
