QUESTION 30 Consider this question: For a certain set of data, what percentage of individuals would have a z-score greater than 1.08? (Hint: this is asking what percentage of the normal curve would fall above that z-score.) (Hint: think about where this z-score is located in relation to the mean. Think about the direction being asked about - (less than or greater than) that value). Which choice below is true? A. The answer will be 100%. B. The answer will...

Proportions (percentages) in a Z Distribution A large population of scores from a standardized test are normally distributed with a population mean (μ) of 50 and a standard deviation (σ) of 5. Because the scores are normally distributed, the whole population can be converted into a Z distribution. Because the Z distribution has symmetrical bell shape with known properties, it’s possible to mathematically figure out the percentage of scores within any specified area in the distribution. The Z table provides...
