%Working	68	45	73	54	61
%Management	49	21	66	47	33

Develop the estimated regression equation by computing the values b₀ and b₁.

Enter negative values as negative numbers. Round your answers to one decimal place.
ŷ = ? + ? x

d. Predict the percentage of management jobs held by women in a company that has 60% women employees. Round your answers to nearest whole value.
? %

Answer 1

)b) b0=-35.0 , b1=1.3 and

(c) ŷ = b0 + b1*x= - 35.0+1.3*x

(d) 43% of management jobs held by women in a company that has 60% women employees.

for x=60, ŷ=-35.0+1.3*60=43%

	%Working(x)	%Management(y)
	68	49
	45	21
	73	66
	54	47
	61	33
mean=	60.2	43.2
variance	98.96	232.96
covariance	128.56
b1=cov(x,y)/var(x)=	1.299110752
b0=mean(y)-b1*mean(x)=	-35.0065
