What sampling distribution will you use? Student's t chi-square binomial O uniform normal What are the degrees of freedom? 4 (c) Find or estimate the P-value of the sample test statistic. (Round your answer to three decimal places.) (d) Based on your answers in parts (a) to (c), will you reject or fail to reject the null hypothesis that the population fits the specified dis Since the P-value > a, we fail to reject the null hypothesis. Since the P-value > a, we reject the null hypothesis. Since the P-value s a, we reject the null hypothesis. Since the P-value <a, we fail to reject the null hypothesis. (e) Interpret your conclusion in the context of the application. At the 5% level of significance, the evidence is sufficient to conclude that the community household distribution does not fit the O At the 5% level of significance, the evidence is insufficient to conclude that the community household distribution does not fit t distribution.

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. Percent of U.S. Households Observed Number of Households in the Community Type of Household Married with children 26% 108 Married, no children 29% 101 Single parent 9% 37 One person 25% 102 Other (e.g., roommates, siblings) 11% 63 A USE SALT 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? 0.05 State the null and alternate hypotheses. Ho: The distributions are the same. H,: The distributions are different. O Ho: The distributions are different..
