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, 396 of 1132 adults with children under the age of 18 reported that their family ate dinnertogether 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-pPo) = 10 and the sample size is(Round to one decimal place as needed.)5% of the population size, and the sampleV the requirements for testing the hypothesisV satisfiedWhat are the null and alternative hypotheses?V versus H, OHo(Type integers or decimals.

Choose the correct answer belowO A. Yes, there is sufficient evidence because the P-value is greater than the level of significance. Therefore, reject the null hypothesis.OB. No, there is not sufficient evidence because the P-value is greater than the level of significance. Therefore, reject the null hypothesis.Oc. Yes, there is sufficient evidence because the P-value is greater than the level of significance. Therefore, do not reject the null hypothesis.OD. No, there is not sufficient evidence because the P-value is greater than the level of significance. Therefore, do not reject the null hypothesis.
