March 27 of 2023Version 3.7 changes:Up to date Build of APP.
August of 2020Version 3.2 changes:Up to date Build of APP.
July of 2019.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 2.9Add Permutations and Combinations.Add Sample Size Calculation.Convenient, Accurate, Easy to Readelectronic Probability Distribution Tables.Normal, Binomial, Poisson, T and FDistributions.
Also, invNorm andinvT calculations.Contains calculators for ConfidenceIntervals (Sigma Known, Sigma Unknown, Proportion).Contains calculators for Permutationsand 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 Statisticscourses, or if you just need these tables!For both Phone and 10 tablets.These tables give you the probabilitiesassociated with your test statistics andparameters.To use these tables, just select thedistribution you want, and put in thetest statistic and parameters, and theAPP tells you the related probability.*************************************1) For the Normal Distribution:Enter your Z Score, and you getthe left, right tails and the range.2) For the Binomial Distribution:Enter n - number of trials,p - probability of success,x - number of successesand you get the probability ofx, or the cumulative probabilityfor x.3) For the Poisson Distribution:Enter the mean, and number ofoccurences, and you will getthe Probability of the numberof occurences, and the cumulativeprobability.4) For the t Distribution:Enter t and the Degrees of Freedomand you will get the probabilityof the left and right tails, andthe two tailed probability.5) For the f Distribution:Enter the f statistic, and theDegrees of Freedom for the numeratorand denominator.
You will get theprobability for the right tail(alpha for the ANOVA test).6) For the Chi-Square Distribution:Enter Chi-Square and the Degrees of Freedomand you will get the probabilityof the right tail.7) Inverse Normal.Enter the probability of theNormal Distribution left tail,and you get the Z statistic.8) Inverse tEnter the probability of thet distribution left tail, along withthe degrees of freedom, and you willget the t statistic.Confidence Intervals:Sigma Known.
Uses the standardCI formula (Using Z) to determine the range withCI% chance of containing the true meanof the population.Sigma unKnown.
Uses the standardCI formula (Using t) to determine the range withCI% chance of containing the true meanof the population.CI for a proportion.
Uses the standardCI formula (Using p,n,Z) to determine the range withCI% chance of containing the true meanof the population.StatUtils:Permutations and Combinations give numberof ways to select n Items out of N Items.In Permutations Order of selected Items matters,in Combinations it does not.
Sampling iswithout replacement.Sample size n, is number needed for CI withfollowing parameters:alpha - CI between 0 and 1.0sigma - Known standard deviation.E - desired error.Formula is: n = (Z^2 * s^2) / E^2Z is Z score for (1-alpha)/2Free, but please visit this APP inthe Google Play store to Rate andenter comments.
