Date High Temperature Subtract previous temperature from current temperature Difference Low Temperature Subtract previous temperature from current temperature Difference 1 89 -N/A- -N/A- 76 -N/A- -N/A- 2 90 89-90 -1 75 76-75 1 3 85 90-85 5 75 75-75 0 4 82 85-82 3 76 75-76 -1 5 83 82-83 -1 75 76-75 1 6 84 83-84 -1 74 75-74 1 7 86 84-86 -2 73 74-73 1 B. Note: The columns for Day One's subtraction and difference cannot be filled in. As this is the first data point, there is no previous temperature to subtract. C. Write a mathematical expression using the information from your table to answer the following questions: 1. What is the mean change in the forecasted high temperatures? Remember, this can be found by averaging the values in the Difference column for the high temperatures. Show your work and steps. If your answer is not an integer, explain what two integers your answer is between. 2. What is the mean change in the forecasted low temperatures? Remember, this can be found by averaging the values in the Difference column for the low temperatures. If your answer is not an integer, explain what two integers your answer is between.
