What would be the predicted stock return for a company whose CEO made $15 million? ?% (Type an integer or decimal rounded to one decimal place as needed) What would be the predicted stock return for a company whose CEO made $25 million? ?% (Type an integer or decimal rounded to one decimal place as needed )

Explanation / Answer

Rcode::

lm function to fit a linear model.

compensation <- c(26.02,12.63,19.86,13.48,12.65,12.33,26.12,15.26,17.18,14.65)
stockreturn <- c(5.66,29.94,31.45,80.25,-8.57,2.75,4.12,10.56,4.06,11.55)
rmod=lm(stockreturn~compensation)
newdata = data.frame(compensation=15)

predict(rmod, newdata, interval="predict")

output:

fit lwr upr
1 19.23219 -44.6649 83.12927

predicted =19.2%

Solutionb:

newdata1 = data.frame(compensation=25)
predict(rmod, newdata1, interval="predict")

fit lwr upr
1 9.047905 -61.26182 79.35763

predicted=9.0%

cor(compensation,stockreturn)

r=-0.2135
