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. 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. (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)
Fоr this prоblem yоu cаn either just give аll аnswers on your work sheet, or you can give a and b on the work sheet and type in answers here for c and d: a) Sketch 2 scatterplots showing negative linear correlation. Make 1 scatterplot so that it shows a significantly stronger correlation. Label that one "stronger correlation" b) Sketch a rough boxplot with no outliers so that the mean would be less than the median. c) If an original sample consisted of these 5 values, {5, 8, 12, 15, 19}, give 2 possible bootstrap samples. d) Using the original sample from part c above, give a specific reason why each sample below couldn't be a bootstrap sample: i. { 5, 5, 8, 19} ii. {5, 8, 12, 17, 19}
