1. Below I have provided you with a graph of some data with the regression line showing. These data test whether sleep is related to cognitive function. 1. What is the regression equation used to obtain predicted scores for cognitive function from the number of hours of sleep? 2. Using the regression equation, what will the predicted score for cognitive function be if a person reports that they get 6.7 hours of sleep? 140,00- 120.00- O function 100.00- y=-4 02+12 59*x O 80.00- 60,00- 5.00 6.00 7.00 8.00 9.00 10.00 sleepPart I An investigator is interested in whether hourly wage relates to morale. 1) Write the null and research hypotheses for the relationship wages and morale functioning in regular prose-Be sure to use HO/H1 form and to state your hypothesis in a complete sentence. Hourly Wage (in dollars) Morale (1-10) 12.00 5 22.00 6 35.00 4 9.00 3 12.00 7 8.00 2 15.00 9 2) Fill in the table below by computing using the data above. n = SX = Ty = Ex? = Syz = Exy = 3) Computer (the correlation coefficient) by hand using the results from part 3. 4) Is it significant? Determine this by using the critical values table. 5) What is 72? How is this number interpreted? 6) Report your full results in APA-formatted sentences
