(V.S.) "I first bought one of these programs for my college algebra class over 2 years ago and loved it. I do not think I would have passed my class without it. Since then I have bought 10 of these programs and find uses for them everyday in my job. I used the statistics and the business programs for my Six Sigma master certificate 6 months ago. Let me tell you, these programs were a lifesaver as my six sigma black belt project concentrated heavily on statistics. I would highly recommend these programs to anyone who is looking to succeed."
(S.P.) "Just wanted to say thanks for a great product and great support, I passed business statistics thanks to you guys, my F went from a 59 to a 80 thanks to the 96 I got on my Finale. All because your product was easy to use."

Description
Users have boosted their Statistics and Probability knowledge.
Shows Step by Step solutions for most Statistics and Probability topics.
Step by Step Confidence Intervals for mean, proportion, 2 means, 2 proportions, variance, slope, etc.
Compute Sample Sizes for Confidence Intervals.
Step by Step Tests of Significance (Z-Tests, T-Tests, ChiSquare Goodness of Fit and Independence tests, 2-sample T tests, 2 proportion Z tests, for Variance, etc)

Read about how Confidence Intervals behave.
Read about Significant Tests: Type 1 Error, Type 2 Error, Power of a Test.
Much easier handling than other Statistics packages: Choose to enter Data or Statistic values. Select Significant/Confidence Levels easily.
Distributions: compute probabilities, etc.
Includes Binomial, Geometric, Normal, Student-t, Exponential, Poisson, Multinomial, Hypergeometric, F-, Chi-Square and more Distributions.
Probability Checker for independent events, disjoint events. Also solves P(A or B)=P(A)+P(B)-P(A and B) for the unknown.
