Janice and Paul did a study on feelings of stress and life satisfaction. Participants completed a measure on how stressed they were feeling (on a 1 to 30 scale) and a measure of how satisfied they felt with their lives (measured on a 1 to 10 scale). The table below indicates the participants' scores. Using this data, answer the following questions: Student Student GPA Motivation Joe 2.0 50 Lisa | 2.0 48 Mary 2.0 100 Sam 2.0 12 Sally 2.1 77 Tony 2.2 66 Katy 2.2 69 Deana 2.3 34 Jenny 2.4 32 Roberto 2.5 58 Sarah 2.6 30 Jennifer 2.6 78 Camilo 2.7 76 Gregory 3.0 87 Thomas 3.1 84 Cindy 3.2 75 Martha 3.6 83 Steve 3.8 90 Jamell 3.8 90 Tammie 4.0 98 1) Draw a scatter plot graph to identify the relationship between students' achievement motivation and GPA. 2) Calculate the sample mean for each variable and sample covariance. Interpret the results. 3) Find the sample standard deviation for each variable and the sample coefficient of correlation. Interpret the results.
