    1. Population mean = 19.1
    15% of data 22.6
    Find standard deviation.

    2. Population mean 120
    Standard deviation 5.7
    What is the probability an individual between 120 and 121.3?

    3. Population mean 120
    Standard deviation 5.3
    Sample n =30
    Find probability that the sample mean is between 120 and 121.8.

    4. Theatre has 150 seats
    Normally 5% no shows (fully occupied)
    Find the probability 11 or more seats are no shows.

    5. Probability of activity= .54
    Sample n =530
    Find the probability that at least 261 of n is active.

    6. Probability of activity .53
    Sample n =192
    Find probability active in n >89<109.

    7. Women = 26% of unquantified group
    Sample n of group = 358
    Find the probability > 112 women in n.

    8. Probability x = .77
    Sample n =300
    Find probability > 54 are not x
