We use the regression equation to predict a step length fromhuman height.

The regression equation is:

What the step length does the model predict for a human heightof 65 inches? What the step length is predicted for a human heightof 75 inches?

Step length (inches)	Height (inches)
25.6	65.4
26	66.2
26.3	67.6
26.6	66
27	70
27.3	72
27.5	70.3
28	69.4
28.4	69.8
29.1	70
29.3	70.4
29.5	71.4
29.7	70.5
29.8	69
30	73
30.5	74
31	73.2
31.5	72.5

Use technology and the given dataset to find and interpret a 95%confidence interval for the mean the step length of humans whoheight of 75 inches.

This is the answer:

However, I'm confused on how toget to this conclusion. Please help!

= - Step 12.432 +0.585 Height
