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, 1128 adults with
children under the age of 18 were selected at​ random, and 399 of
those 1128 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 α=0.1
significance level.

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, 1128 adults with children under the age of 18 were selected at random, and 399 of those 1128 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. 5% of the population size, and the adults in the sample selected at random, all of the requirements for testing the hypothesis satisfied. Because npo (1-P) 10 and the sample size is (Round to one decimal place as needed.) What are the null and alternative hypotheses? Ho: versus Hy: (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 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.)
