Mar 081 Proportions
Example 1
You are moving into a new apartment, but you cannot move in until the 13h of April so your new prop-
erty owner says that they will prorate your rent (definition of prorate - allocate, distribute, or assess pro-
portionally). If your regularly monthly rent is $1550, use mathematics to figure out how much you should
be paying for the month of April.

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
