Suppose that 42% of students of a high school play video games at least once a month. The computer programming club takes an SRS of 30 students from the population of 792 students at the school and finds that
40% of students sampled play video games at least once a month. The club plans to take more samples like this.
Let represent the proportion of a sample of 30 students who play video games at least once a month.
What are the mean and standard deviation of the sampling distribution of p?
