    A normal population has a mean of 80.0 and a standard deviation of 14.0. Compute the probability of a value between 75.0 and 90.0. Compute the probability of a value 75.0 or less. Compute the probability of a value between 55.0 and 70.0.

    In a binomial situation n = 4 and p = .25. Determine the probabilities of the following events using the binomial formula.
    x = 2
    x = 3

    In a binomial situation n = 5 and p = .40. Determine the probabilities of the following events using the binomial formula.
    x = 1
    x = 2

    The mean rent for a one-bedroom apartment in Southern California is $2,200 per month. The distribution of the monthly costs does not follow the normal distribution. In fact, it is positively skewed. What is the probability of selecting a sample of 50 one-bedroom apartments and finding the mean to be at least $1,950 per month? The standard deviation of the sample is $250
