Use z-scores to make the following comparison between students. a. Claudia has a score of 61. Her class had a mean score of 74 and a standard deviation of 4 . Convert Claudia's score to a z- score. b. Isabella has a score of 79. Her class had a mean test score of 82 and a standard deviation of 2. Convert Isabella’s score to a z-score. c. Based on the z-scores, which student did better on their test compared to their class (“had a better relative position”)?

Mr. Stant collected information on how much customers spend at Walmart and Target. He created the following histograms. Which of the statements must be true about the two data sets displayed? a The standard deviation of amounts spent at Walmart is less than the standard deviation of the amounts spent at Target. b The median amount spent at Walmart is equal to the median amount spent at Target. c The standard deviation of amounts spent at Walmart is more than the standard deviation of the amounts spent at Target. d The range of amounts spent at Walmart is equal to the range of amounts spent at Target. e The mean amount spent at Walmart is equal to the mean amount spent at Target.
If your score on your next statistics test is converted to a z score, which of these z scores would you prefer: - 2.00, - 1.00, 0, 1.00, 2.00? Why? OA The z score of 1.00 is most preferable because it is 1.00 standard deviation above the mean and would correspond to an above average test score. O B. The z score of 0 is most preferable because it corresponds to a test score equal to the mean. OC. The z score of - 1.00 is most preferable because it is 1.00 standard deviation below the mean and would correspond to an above average test score. OD. The z score of 2.00 is most preferable because it is 2.00 standard deviations above the mean and would correspond to the highest of the five different possible test scores. O E. The z score of -2.00 is most preferable because it is 2.00 standard deviations below the mean and would correspond to the highest of the five different possible test scores.

A student scores 74 on a geography test and 264 on a mathematics test. The geography test has a mean of 80 and a standard deviation of 5. The mathematics test has a mean of 300 and a standard deviation of 24. If the data for both tests are normally distributed, on which test did the student score better relative to the other students in each class? OA. The student scored better on the mathematics test. OB. The student scored better on the geography test. OC. The student scored the same on both tests.
Answer the Ff.
Note: The standard deviation is defined as the average distance of the class scores from the mean. Note: The variance is defined as average squared distance of the class scores from the mean. Sameer's score in a quiz was 25 and he was five standard deviations above the mean in this quiz. The mean was 20. The average squared distance of the scores from the mean in this quiz is: Select one: a. -3 b. 2 c. 3 d. -2 e. 1 f. -1
