    How do I know which distribution to use for the following and when/where do tables apply?:

    Nonstandard Normal
    Binomial
    Normal
    Standard normal
    Central limit theorem

    a) Mean is 0, stand. dev. is 0 degrees C., find P between 0.05 and 1.50
    b)Mean is 63.6 and s.d. is 2.5; Club had requirement that women must be 70 inches tall-what % meets that?
    c)Find the P35 separating top 35 from bottom 65% with mean = 143 and sd. of 29
    d) Mean = 143, sd = 13; if 1 woamn randomly selected, find P weight between 143 and 150
    e) If 100 women randomly selected, find P they have a mean weight greater than 140 pounds.

    Nonstandard Normal: This type of distribution is applicable specifically when the sample size is small and the you are given that the data are not Guassian/Normal distributed. i.e.,
    P(mu - sigma < x < mu+sigma) =! 68%
    or
    P(mu - 2sigma < x < mu + 2 sigma) =! 95%
    Also the distribution may have some skewness.

    Binomial distribution is used when the probability of an event is ...
