Interpret the results. Since the P-value is than a, the null hypothesis. There sufficient evidence at the a = level of significance to conclude that the proportion of families with children under the age of 18 who eat dinner together seven nights a week is (Type integers or decimals. Do not round.)In a previous poll, 40% of adults with children under the age of 18 reported that their family ate dinner together seven nights a week. Suppose that, in a more recent poll, 1123 adults with children under the age of 18 were selected at random, and 428 of those 1123 adults reported that their family ate dinner together seven nights a week. Is there sufficient evidence that the proportion of families with children under the age of 18 who eat dinner together seven nights a week has decreased? Use the a = 0.05 significance level. Because npo (1 - Po ) = 10 and the sample size is 5% of the population size, and the adults in the sample selected at random, all of the requirements for testing the hypothesis satisfied [Round to one decimal place as needed.) What are the null and alternative hypotheses? Ho: versus H1: V (Type integers or decimals. Do not round.) Find the test statistic, Zo. Zo =(Round to two decimal places as needed.) Find the P-value. P-value = (Round to three decimal places as needed.)
