SOLUTIONS 26) ANS: STEP 1: Input the data in the stats editor of a graphing calculator and calculate linear regression. PTS: 2 NAT: S.ID.B.6a TOP: Regression 27) ANS: The data appear to grow at an exponential rate. Part a: Part b: Strategy: Input the data into a graphing calculator, inspect the data cloud, and find a regression equation to model the data table, input the regression equation into the y-editor, predict the missing value. STEP 1. Input the data into a graphing calculator or plot the data cloud on a graph, if necessary,  so that you can look at the data cloud to see if it has a recognizable shape. STEP 2. Determine regression strategy will best fit the data. The graph looks like the graph of  an exponential function, so choose exponential regression. Execute the appropriate regression strategy in the graphing calculator. STEP 3.  Round all values to the nearest hundredth: STEP 4. Input the regression equation into the y-editor feature of the graphing calculator and view  the associated table of values to find the value of y when x equals 2. Round 3515.3 to 3515. In STEP 4.  Ask the question, it Make Sense (DIMS)?” that the missing total number of views in month 2 “Does would be around 3515 views? PTS: 4 NAT: S.ID.B.6a TOP: Regression 28) ANS: 4 Strategy: Input the data into a graphing calculator, inspect the data cloud, and find a regression equation to model the data table, input the regression equation into the y-editor, predict the missing value. STEP 1. Input the data into a graphing calculator or plot the data cloud on a graph, if necessary,  so that you can look at the data cloud to see if it has a recognizable shape. STEP 2. Determine which regression strategy will best fit the data. The graph looks like the graph  of an linear function, so choose linear regression. STEP 3. Execute the appropriate regression strategy in the graphing calculator.  Write the regression equation in a format that can be compared to the answer choices: Compare the answer choices to the regression equation and select choice d.
