The table below shows the arm spans (in inches) and the heights (in inches) of 10 randomly selected people.

Arm Span, x 51 52 56 49 54 59 58 55 52 56
Height, y 51 53 54 50 55 57 58 57 52 56

1) Construct the 1% confidence interval for the population slope β 1. Make sure your answers follow the rounding rule in the direction.

Lower endpoint =

Upper endpoint =

2) Fill in the blanks in the following statement.

We are 99% confident that, among all people, for each additional inch in the arm span, the average height increases by between  inches and  inches.
