4. In Uganda only 9% of the population has access to electricity. Suppose we randomly sample 20 people in Uganda. Let X be the number of people in our sample who have access to electricity. (a) What distribution will X have? (Hint: X only takes on the values 0, 1, ... 19, 20, so it can't be a continuous distribution.) (b) Find the mean and standard deviation for X. (c) Find the probability that 10 people or less in the...
