    Description

    Version 3.1 changes:

    Now you can choose to show or omit background graphs on the Probability Table text views. Choose how you want it on the About Screen. Also, you can now copy the Probability Table text results from the answer in the Probability Table text views.

    Version 3.0 includes:

    Hypothesis Test Mean (Sigma Known, Sigma
    Unknown, Proportion).
    Inference Test Formulas for 2 Populations -
    Means and Proportions.

    Version 2.9
    Add Permutations and Combinations.
    Add Sample Size Calculation.

    Convenient, Accurate, Easy to Read
    electronic Probability Distribution Tables.

    Normal, Binomial, Poisson, T and F
    Distributions. Also, invNorm and
    invT calculations.

    Contains calculators for Confidence
    Intervals (Sigma Known, Sigma Unknown,
    Proportion).

    Contains calculators for Permutations
    and Combinations, and Sample Size.

    Updated to include:

    Hypothesis Test Mean (Sigma Known, Sigma
    Unknown, Proportion).
    Inference Test Formulas for 2 Populations -
    Means and Proportions.

    Great for Intro Probability Statistics
    courses, or if you just need these tables!

    For both Phone and 10' tablets.

    These tables give you the probabilities
    associated with your test statistics and
    parameters.

    To use these tables, just select the
    distribution you want, and put in the
    test statistic and parameters, and the
    APP tells you the related probability.

    *************************************

    1) For the Normal Distribution:

    Enter your Z Score, and you get
    the left, right tails and the range.

    2) For the Binomial Distribution:

    Enter n - number of trials,
    p - probability of success,
    x - number of successes

    and you get the probability of
    x, or the cumulative probability
    for x.

    3) For the Poisson Distribution:

    Enter the mean, and number of
    occurences, and you will get
    the Probability of the number
    of occurences, and the cumulative
    probability.

    4) For the t Distribution:

    Enter t and the Degrees of Freedom
    and you will get the probability
    of the left and right tails, and
    the two tailed probability.

    5) For the f Distribution:

    Enter the f statistic, and the
    Degrees of Freedom for the numerator
    and denominator. You will get the
    probability for the right tail
    (alpha for the ANOVA test).

    6) For the Chi-Square Distribution:

    Enter Chi-Square and the Degrees of Freedom
    and you will get the probability
    of the right tail.

    7) Inverse Normal.

    Enter the probability of the
    Normal Distribution left tail,
    and you get the Z statistic.

    8) Inverse t

    Enter the probability of the
    t distribution left tail, along with
    the degrees of freedom, and you will
    get the t statistic.

    Confidence Intervals:

    Sigma Known. Uses the standard
    CI formula (Using Z) to determine the range with
    CI% chance of containing the true mean
    of the population.

    Sigma unKnown. Uses the standard
    CI formula (Using t) to determine the range with
    CI% chance of containing the true mean
    of the population.

    CI for a proportion. Uses the standard
    CI formula (Using p,n,Z) to determine the range with
    CI% chance of containing the true mean
    of the population.

    StatUtils:

    Permutations and Combinations give number
    of ways to select n Items out of N Items.
    In Permutations Order of selected Items matters,
    in Combinations it does not. Sampling is
    without replacement.

    Sample size n, is number needed for CI with
    following parameters:

    alpha - CI between 0 and 1.0
    sigma - Known standard deviation.
    E - desired error.

    Formula is: n = (Z^2 * s^2) / E^2

    Z is Z score for (1-alpha)/2
