The z-score is as important of a concept as the value we are trying to find and the connection between the two is critical; this is not just an academic exercise. It is common to use this type of communication when using statistics. I will use software to find the associated z-score P(Z > z) = 0.05; z ( 1.645.

Using the table, a z-score of -1.5 or lower corresponds to a probability of .4332 ( P(score ≤ 60) = .5 - .4332 =.0668 What is the probability that someone would score between an 80 and a 90? Using the table, a z-score of .25 corresponds to a probability of .0987. Using the table, a z-score of .375 corresponds to a probability of .1480

Problem 3 – Small Sample, = 0.05. Suppose that the sample mean and standard deviation ($45,742 and $14,192) came from a sample of 25 residents instead of 100 residents. 11. Will you find a z-score or a t-score? Why? 12. Calculate the test statistic. 13. Calculate the critical value by using the . invT . command. It is located in the [DISTR ...

We also assume that the standard deviation is 20 and the alpha is 0.05. We want to find out the corresponding sample size for each power level ranging from 0.8 to 0.99 at 0.01 intervals. The outputs should look like the following: One-Way ANOVA # Treatments = 2 CSS of Means = 50. Standard Deviation = 20 Alpha = 0.05. N per. Power Group
