Concept explainers

Inverse Normal Distribution

The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.

Mean, Median, Mode

It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.

Z-Scores

A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.

This question test your understanding of the z-test One hundred investigators set out to test the null hypothesis that the average of the numbers in a certain box equals 50 against the alternative hypothesis that the average is greater than 50. Unknown to the investigators, the null hypothesis is true. Each investigator takes 250 tickets at random with replacement (this is the sample size), computes the average of the draws, and does a z-test. The z-test statistics obtained by each investigator are plotted in the diagram. Observe, for example that Investigator #1 got a z-statistic of 1.9, which is plotted as the point (1, 1.9). Investigator #2 got a z-statistic of 0.8, which is plotted as the point (2, 0.8), and so forth. If z = 2, what is the p-value? Use 3 decimals.
