What ero the null and alternative hypotheses? H, V versus H, (Type integers or decimals. Do not round) Find the test statistic, zo 20=(Round to two decimal places as needed Find the P-value P.value = (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 i significance Therefore, reject the null hypothesis O A. No, there is not sufficient evidence because the P-value is greater than the level O B. Yes, there is sufficient evidence because the P-value is greater than the level of significance. Therefore, do not reject the null hypothesis OC. Yes, there is sufficient evidence because the P-value is greater than the level of significance. Therefore, reject the null hypothesis O D. No, there is not sufficient evidence because the P-value is greater than the level of significance. Therefore, do not reject the null hypothesis

Question
In a previous pollI, 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 polI, 387 of 1109 adults with children under the age of 18 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=0.01 significance level. Because npo (1- Po) = 10 and the sample size is V 5% of the population size, and the sample V the requirements for testing the hypothesis V satisfied. (Round to one decimal place as needed.) What ere the null and alternative hypotheses? V versus H, Type integers or decimals. Do not round.) Find the test statistic, Zo 20= (Round to two decimal places as needed) Find the P-value Pvalue = (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 O A. No, there is not sufficient evidence because the P-value is greater than the level of significance. Therefore, reject the null hypothesis O B. Yes, there is sufficient evidence because the P-value is greater than the level of significance. Therefore, do not reject the null hypothesis. O C. Yes, there is sufficient evidence because the P-value is greater than the level of significance. Therefore, reject the null hypothesis O D. No, there is not sufficient evidence because the P-value is greater than the level of significance. Therefore, do not reject the null hypothesis.
