Scenario and data: A group of 8 college students participated in a study of nutritional awareness. Their scores are: 5, 3, 4, 3, 2, 6 Compute the following using the sample data above (and formulas). Use three decimal places for all final answers. a) Sample mean (X̄)b) Sample variance (Sₓ²)c) Sample standard deviation (Sₓ)d) z-score for the raw score x = 3 (use the sample mean and sample standard deviation you compute above)e) What is the proportion of scores between the mean and x = 3 (compute a z-score and use the z-table) Enter your answers in the Canvas response box below in this format (answers must be labeled):a =b =c =d =e = If answers are not labeled, you will not receive credit. You must enter all final answers in the response box. Uploading work does NOT replace entering answers in Canvas.  Points: a = 1, b = 2, c = 1, d = 1, e = 1 (Total = 6 points) Manual work upload: Upload a clear PHOTO of your handwritten computations showing the formulas and ALL STEPS leading to your answers (upload under each question using the insert picture button, or in the comment section of the exam). This is required to verify you did your own work and get credit. Enter answers in the exam response box on Canvas still. You will lose credit if you do not answer questions in the response box and only upload your work. 

Look to see if the following graph indicates the existence of a relationship between the amount of hours doing yoga and the level of stress. Answer the following questions:   a) Does the line show the existence of a relationship? yes or no?  [relationship]  AND if yes, b) which type of relationship is it, positive or negative? [direction]     

A survey measuring stress produces normally distributed scores. If your score is at the 34th percentile, where do you fall in relation to the mean—above or below?

In a statistics test where the mean is 38, and the standard deviation is 2,  suppose you are told that you scored two standard deviations above the mean. What is your score? (enter the number only)
