A binоmiаl experiment is cоnducted where 100 hоmes аre selected аt random, and each home is asked whether or not they have a metal roof. (Binomial experiment) A recent study shows that 39% of homes have a metal roof. You select 100 homes at random. [a] What is the mean number of houses with a metal roof? (39% have them; 100 homes surveyed) [b] What is the standard deviation of this binomial experiment? You want to know how likely it is that at least 34 of the 100 homes selected will have a metal roof, so you ask the question (binomial)...P(x>=34)? The continuity correction that is used to approximate this with a normal distribution is P(x>[c]) [d] Use a normal distribution to approximate the probability that your sample of 100 homes has at least 34 homes with a metal roof. P(x>=34) Round to the nearest percent.
