Question
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 poll, 334 of 1115 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) = 291.8
10 and the sample size is
less than
5% of the population size, and the sample
can be reasonably assumed to be random,
the requirements for testing the hypothesis
are
%3D
satisfied.
(Round to one decimal place as needed.)
What are the null and alternative hypotheses?
Ho:
32 versus H1
32
(Type integers or decimals. Do not round.)
Find the test statistic, 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.

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.
A. Yes, there is sufficient evidence because the P-value is greater than the level of significance. Therefore, reject the null hypothesis.
B. No, there is not sufficient evidence because the P-value is greater than the level of significance. Therefore, reject the null hypothesis.
C. Yes, there is sufficient evidence because the P-value is greater than the level of significance. Therefore, do not reject the null hypothesis.
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.
