Can you help me determine the P value for the following equation?

In a previous poll, 34% 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, 337 of 1064 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) = 238.8 >
> 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
satisfied.
