Question 8- Show work for 1-2. Students of a small university who eat lunch on campus spend an average of $6.25 a day at their cafeteria. The standard deviation of the expenditure is $1.25. The data is normally distributed. 1. What is the z score of Frank who spent $6.00? 2. What probability corresponds with Frank's z score? 3. Why was Frank's z score negative? Why was his probability positive? Doria spent $3.15 on her lunch on Friday. Explain to her, in terms of standard deviation, why this is not a typical expenditure at this campus.

Someone tells you that the mean score on a test was 85, and the standard deviation was -10. What does this mean? A. Need more information to answer this question B. The most common score was 75. C. A majority of the class scored less than 85. D. This is not possible. Standard deviation cannot be negative.

Suppose you have already calculated the mean, the average deviation, and the standard deviation of the weights in pounds of 20 third-graders. a. if these weights were converted to kilograms and the mean and the average deviation were once again calculated, would the second average deviation be (numerically) less than, greater than, or equal to the first average deviation? Explain your answer. b. If the standard deviation of these weights were calculated in kilograms, would it be (numerically) less than, greater than, or equal to the first standard deviation? Explain your answer
I’ve already posted this one, but I’m posting it again, because I need to be shown what to input into my TI-84 Plus calculator to solve.
You determine that the standard deviation for a sample of test scores is 0. This tells you that 1 all the test scores must be 0. 2 all the test scores must be the same value. 3 there is no straight-line association. 4 the mean test score must also be 0. 5 you made a mistake because the standard deviation can never be 0.
