1.Out of $550,000.00 given to a school, an amount of $325,000.00 was used. What fraction of the total amount was used? 2. Arrange the following fractions in ascending order: 7/12, 3/5, 7/15, 3/4. 3. Simplify 1/3 (1/2 - 1/3) - 1/3 (1/3 - 1/2)

If your score on your next statistics test is converted to a z score, which of these z scores would you prefer: minus2.00, minus1.00, 0, 1.00, 2.00? why? a. 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. b. the z score of 0 is most preferable because it corresponds to a test score equal to the mean. c. the z score of minus2.00 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. d. the z score of minus1.00 is most preferable because it is 1.00 standard deviation below the mean and would correspond to an above average
