Can you help me with number 2, please?
Complete this Worksheet. You Will need these answers for Homework Assignment #6. 2. As your sample was so small, you want to predict how other participants may answer if you recruited them. To do this you need to nd the linear equation for this data set. 1. You are a researcher interested in time spent in nature and stress. You recruit a small sample and measure how much time they have spent outdoors in the last week (this is variable. X). You also I) : E a : My , bMX )7 : I) X + a measure their self-report of stress (this 15 Variable Y). The participants scores are listed below. You 55" want to know if there is a correlation between time spent outdoors and stress and if so. what type of _ y , _ correlation is it and is it strong or weak. a. Usrng the formulas above, report the linear equation for this data set Complete the following chart Make sure you do NOT round your answers until you report them on the assignment. Every time you round you create errors and can risk throwing your nal answer off b. Given What you found in \"2a", if we invited a 7''1 person in this study and they score 9.5 on X (time outdoors), what do we predict their score will be on Y (stress)? SP r: m SP: ZXX MX)(Y My) or If their actual score is -3.91, what is the error of prediction? X (X-Mx) (X-lVIx)z Y (Y-My) (Y-VIY)1 8 0 6 l 4 4 3 6 4 6 5 1 SSx= 16 SSv= 36 SP: >21 r = -0.875 a. W at direction is the correlation positive or negative? 9 Here, the coefficient of correlation is r = -0.875 which have negative magnitude. Twus. the direction of correlation is negative. b. Wiat is the strength of the correlation 7 weak, moderate. or strong? Make sure you review the Cohen's cutoffs for this, a Here, the absolute value of correlation is |r| = |0.875| > % Le. M > dim Thus, the strength of the correlation is strongStep by Step Solution
