I'm not sure how to solve this problem:

The cable company takes an SRS of 250 of households who subscribe to them. They have found that 74% of the sampled households watch sports on television at least once a month. The company is considering taking more samples like this. Suppose that it is actually 70% of their total subscribed households who watch those sports. Let p^ represent the proportion of the sample that watch sports on television at least once a month. Find the following p, q, n, p^, q^ Find the mean and standard deviation of the sampling distribution of p^
