As of October 2012 approximately 72% of all American households have high speed internet access. Consider a random sample of 40 American households. Assuming that each house has a 72% chance of having high- speed internet access and that the results are independent determine…. a.) Determine probability that exactly 30 of the 40 american households have high speed internet access. b.) Determine probability that between 27 and 29 American households have high- speed internet access. (i.e at least 27 but no more than 29 American households) c.) What is the mean and standard deviation of this random variable?
