You have just read an article which estimates the starting annual salary (M - 46.4 4-. 4.2} of college graduates based on the number of STEM. courses {M - 6.1 s 2.8} taken to earn their degree. The paper states, \"the annual salary, reported in $1000, is related to the number of STEM courses {b - 0.396} and this relationship is statistically significant {Flhhi - 6.30, p - 1115)." Though not required to be entered here, be sure to interpret the slope for this model. (1) Give the sample size for this analysis. e n = (2) Use the information provided to calculate the full equation for this linear model.
