Fоr this prоblem we will аccess а dаta set in stat key where researchers recоrded the values of the temperature in degrees F and the number of chirps they could hear a cricket make. Access this data set in the 2 quantitative variable section of stat key. Use the drop down menu to select the data set "Cricket chirps (temp vs chirps)". You can access stat key by entering the url lock5stat.com into the url bar of chrome browser, or you can find a link to stat key by clicking on "assessment details" on your screen. You should see a scatterplot and a statistics table - but the display shows the chirps as the x and the temperature as the y and we should switch that. To switch the variables, over by the summary statistics table click on "switch variables". You should now see temperature as the x and chirps as the y. Answer the questions below: a) Write the equation of the regression line using the appropriate values from stat key. You don't need to worry about using the "hat" notation. ( 3 points) b) Write a sentence interpreting the slope, fully, and in context. (4 points) c) Predict the number of chirps we could expect to hear on a 70-degree day. Give the answer here but show how you arrived at the answer using your regression equation on your work sheet. Label this problem 3c (3 points) d) Could we get a reliable prediction for the number of chirps on a 5-degree day? Why or why not? (2 points)
