Suppose X is a binomial random variable that models the number of successes in n trials, where each trial is a success with probability p. The sample proportion of successes p_hat is related to the binomial random variable X in that a. P(p_hat = x) = P(X = x) b. P(p_hat = x/n) = P(X = x) c. P(p_hat = n/x) = P(X = x) d. P(p_hat = x) = P(X = x/n)

At a toll-booth on-ramp there is a stochastic arrival distribution. Vehicles are counted in 20-second intervals, and vehicle counts are taken in 120 of these time intervals. Based on data collected, no vehicles arrived in 18 of the 120 count intervals. What is the number of the 120 intervals that 3 cars arrived?

Let a be a random variable representing the percentage of protein content for early bloom alfalfa hay. The average percentage protein content of such early bloom alfalfa should be u = 17.2%. A farmer's co-op is thinking of buying a large amount of baled hay but suspects that the hay is from a later summer cutting with lower protein content. A small amount of hay was removed from each bale of a random sample of 50 bales. The average protein content from the samples was determined by a local agricultural college to be -15.8% with a sample standard deviation of S = 5.3%- At a = .05, does this hay have lower average protein content than the early bloom alfalfa?
