Question

Answer True or False to each of the following.

The terms “independent” variable and “predictor” variable are synonymous.

If a test is run and p=0.04, then we can reject H0 at a=0.01.

The larger the n, the wider the confidence interval.

When r=1, all of the change in Y is explained by changes in X.

1. The terms “independent” variable and “predictor” variable are synonymous. - TRUE

since independent variable is nothing but predictor variable

2. If a test is run and p=0.04, then we can reject H0 at a=0.01. - FALSE

since P-value > alpha 0.01 so we accept H0 but given reject H0

3. The larger the n, the wider the confidence interval. - FALSE

Since As n is large then the shorter the confidence interval

4. When r=1, all of the change in Y is explained by changes in X. - TRUE

since it is perfect correlation
