When developing an interval estimate for the difference between two sample means, with sample
sizes of n and n2,
n1 must be larger than n2
O ni must be equal to n2
ni must be smaller than n2
O n1 and n2 can be of different sizes

In a regression line, the

the standard error of the estimate is, the more accurate the
O The standard error of the estimate is not related to the accuracy of the predictions.
Larger
Smaller
When you calculate your regression line, you are:
Finding the absolute value of the error terms and minimizing the sum of the absolute values
O Minimizing the sum of the errors
O Finding the error for each observation, squaring the error and minimizing the sum
