Q1, Mulitple R 0.32923

R Square 0.50832

Coefficients

Intercept 99.0000

Heels -7.5000

Given the above data, what is the regression equation?

a,y = 99 - 7.5(Heels)

b,y = -7.5 + 99(Heels)

c,r 2 = .508

d,y = 99 + 7.5(Heels)

Q2, What is the Binomial Probability if the number of trials are 14, probability is 0.54, and we want exactly 2 successes.

a, 0.0024

b, 0.0027

c,.9973

D,.9997

Q3, What is the Hypothesis Test of Proportion where the claim for a marketing campaign is that 0.65 clients respond, and you want to prove it is less. Your survey of 116 clients showed 80 respond. Test the hypothesis at a 5 % level of significance.What is the decision rule for the above?

a,-1.28

b,-1.64

c,-2.33

d, I used to be indecisive on decisions, now I am not sure.

Q4, Calculate the Discrete Variance using these numbers:

a, x = 0 P(X = x)= 0.12

b,x = 1 P(X = x)= 0.13

c,x = 2 P(X = x)= 0.04

d,x = 3 P(X = x)= 0.71
