In a previous poll, 37% 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, 1101 adults with children under the age o 18 were selected at random, and 389 of those 1101 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=0.1 significance level. Because npo (1-Po) satisfied. (Round to one decimal place as needed.) What are the null and alternative hypotheses? 10 and the sample size is 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.) Interpret the results. Since the P-value is than a of 18 who eat dinner together seven nights a week is EEEE 5% of the population size, and the adults in the sample the null hypothesis. There selected at random, all of the requirements for testing the hypothesis sufficient evidence at the a= level of significance to conclude that the proportion of families with children under the age
