Suppose that student’s z score is 3.00 what does this mean? discuss in terms of units of standard deviation It means the value defined by z-score is 3 standard deviations away from the mean value. Discuss in terms of its percentile score. In terms of percentile score, its mean amount of data lies below the value. Z=3 represent the 99.87 the percentile. 4. How does this student’s z score differ from another student whose z score is -3.00 5. If...

In a normal distribution, the mean corresponds to: Standard Score: z = Percentile: Which of the following statements are TRUE about the normal distribution? Check all that apply. A data value with z-score = -1.5 is located 1.5 standard deviations below the mean. The mean corresponds to the z-score of 1. The Empirical Rule only applies when a value is exactly 1, 2, or 3 standard deviations away from the mean. A z-score is the number of standard deviations a...

and interpret population and sample Z-scores. True or False (if any component is false, state why): Suppose in a standardized test which has a mean score of 530 and a standard deviation score of 50, you score a 605. This gives you a z-score of (605 - 530) / 50 = 1.5, meaning that your score was 1.5 standard deviations above the mean, which is a fairly good score. 11- Apply basic probability rules and concepts to determine the likelihood...
