Question

1. Under what conditions are the computed p-values for these tests valid?

2. Assuming those conditions are satisfied, which of the following gives a correct interpretation of the p-value of T/S Ratio?

a. At the 10% significance level, T/S Ratio is a significant linear predictor.

b. At the 10% significance level, T/S is a significant linear predictor in combination with %Takers.

c. At the 5% significance level, T/S Ratio is not a significant linear predictor in combination with %Takers.

d. Both b and c.

Explanation / Answer

1. Suppose the variables, Score and % takers satisfy assumption sfor regression inference, then for each value of score, the conditional distribution of % takers is a normal distribution with mean bo+b1x and standard deviation sigma.

2. c [p value is not less than alpha=0.05]
