The type of household for the U.S. population and for a random sample of 411 households from a community in Montana are shown below. Observed Number of Households in the Community Percent of U.S. Type of Household Households Married with children 26% 100 Married, no children 29% 107 Single parent 9% 37 One person 25% 102 Other (e.g., roommates, siblings) 11% 65 Use a 5% level of significance to test the claim that the distribution of U.S. households fits the Dove Creek distribution. (a) What is the level of significance? State the null and alternate hypotheses. O Ho: The distributions are different. H,: The distributions are different. O Hn: The distributions are the same. H,: The distributions are the same. O Hn: The distributions are different. H, : The distributions are the same. O Ho: The distributions are the same. H,: The distributions are different. (b) Find the value of the chi-square statistic for the sample. (Round the expected frequencies to two decimal places. Round the test statistic to three decimal places.) Are all the expected frequencies greater than 5? O Yes O No What sampling distribution will you use? O Student's t O normal O chi-square O binomial O uniform What are the degrees of freedom?
