Explanation / Answer

SOlution:

take X as compenstaion

and Ya s stock return.

Linear regression eq

stock return =a+b(compenstaion)

a=y intercept

b is slope

Perform linear regression in R

code is:

compensation <- c(26.83,12.98,19.49,13.46,12.56,12.14,26.53,15.28,17.71,13.93)
stockreturn <- c(5.57,30.37,31.53,79.68,-8.17,2.69,4.22,11.26,4.03,11.38)
print(compensation)
print(stockreturn)
rmod1 <- lm(stockreturn~compensation)
coefficients(rmod1)
cor(stockreturn,compensation)

output:

Intercept) compensation
34.1100757 -0.9861375
> cor(stockreturn,compensation)
[1] -0.2182951

Regresison eq is

stockreturn= 34.1100757-0.9861375(compensation)

What would be the predicted stock return for a company whose CEO made $15 million

x=15

stockreturn= 34.1100757-0.9861375(compensation)

= 34.1100757-0.9861375(15)

=19.31801

=19.3

answer:19.3

What would be the predicted stock return for a company whose CEO made $25 million?

x=25

stock return =34.1100757-0.9861375*(25)

=9.456638

=9.5

ANSWER:9.5
