Question
In a previous poll, 29% 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, 305 of 1126 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 = 0.05 significance level. .... Because npo (1- Po) = 10 and the sample size is greater than 5% of the population size, and the sample can be reasonably assumed to be random, the requirements for testing the hypothesis (Round to one decimal place as needed.) satisfied. What are the null and alternative hypotheses? V versus H,: Ho: (Type integers or decimals. Do not round. Find the test statistic, z,. Zo = |(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. O A. No, there is not sufficient evidence because the P-value is greater than the level of significance. Therefore, do not reject the null hypothesis. O B. Yes, there is sufficient evidence because the P-value is greater than the level of significance. Therefore, reject the null hypothesis. O C. No, there is not sufficient evidence because the P-value is greater than the level of significance. Therefore, reject the null hypothesis. O D. Yes, there is sufficient evidence because the P-value is greater than the level of significance. Therefore, do not reject the null hypothesis.
