Question

In a random sample of sixteen different industries the percentage employment x in STEM (science, technology, engineering, mathematics) and mean annual compensation y(in thousands of dollars) were recorded, with the following results. The scatter diagram showed a linear trend.

SS_xx = 1303.9 SS_xy= 1503.0 SS_yy = 2660.2 Σx = 150 .1 Σy = 915 n = 16

1 ≤ x ≤ 34 36.7 ≤ y ≤ 90.5

Predict the mean annual compensation in industries in which 30 percent of the workforce are in a Stem field. You answer should be entered in thousands of dollars. Example: If you calculate y-hat as 40.6 then the answer you enter should be 40,600
