1. What is the average?

",type:"multi",responses:[{text:"30 degrees",correct:!0},{text:"29 degrees",correct:!1},{text:"30.5 degrees",correct:!1},{text:"27.9 degrees",correct:!1}]},{text:"

2. What is the range of Joe's measurements?

",type:"multi",responses:[{text:"2 degrees",correct:!1},{text:"3 degrees",correct:!1},{text:"4 degrees",correct:!1},{text:"5 degrees",correct:!0}]},{text:"

3a. What is the standard deviation of the numbers? First, compute the deviations from the average (see Question 1). Select the correct answer from the options below.

",type:"multi",responses:[{text:"0, -3, -1, 0, 1, 0, 2",correct:!0},{text:"0, 3, 1, 0, -1, 0, -2",correct:!1}]},{text:"

3b. Compute the sum of the squares of the deviations and select the appropriate answer below.

",type:"multi",responses:[{text:"15",correct:!0},{text:"13",correct:!1}]},{text:"

3c. What is the next step?

",type:"multi",responses:[{text:"Divide the sum by 7.",correct:!1},{text:"Divide the sum by 6.",correct:!0}]},{text:"

4. What is the standard deviation?
