In a previous poll, 32% 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 pol, 334 of 1115 adults with children under the age of 18 reporte 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) = 291.8 > 10 and the sample size is satisfied. (Round to one decimal place as needed.) can be reasonably assumed to be random, the requrements for testing the hypothesis are less than 5% of the population size, and the sample What are the null and alternative hypotheses? Họ: p 32 versus H; p < 32 (Type integers or decimals. Do not round ) Find the test statistic, zo zo = 546.64 (Round to two decimal places as needed.) Find the P-value P-value =746 (Round to three decimal places as needed.) 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? Choose the correct answer below.
