Statistics 5 - Z
... Z-Scores Objective: By the end of the lesson, you should be able to: - Determine the z-score of a given value in a normally distributed data set. - Explain the meaning of a z-score. Key Point: Z-scores allow us to compare data from different normal distributions. We have seen that different standard ...

... Standard_dev is the population standard deviation for the data range and is assumed to be known. Size is the sample size. If we assume alpha equals 0.05, we need to calculate the area under the standard normal curve that equals (1 - alpha), or 95 percent. This value is ± 1.96. The confidence interva ...

... From this experimental data we obtain a probability of 45/100. Is this a theoretical probability or an empirical probability? 15. In the game of "Powerball", 5 white balls are drawn from a tank containing 53 balls numbered 1 through 53, and 1 red "powerball" is drawn from a tank containing 42 balls ...
