Biased because the survey was conducted in a limited field of people aka health club which does not include other people, perhaps an unhealthy club? Or the people who are not a part of the health club? Or people who do not care about their health?
Hey There!

as a mixed number would be

Thank You!
Answer:
Look just at finding the linear model. Two points. Use price per gallon for x and gallons per hour sold for y. Your two points (x,y) are (2.15,1600) and (2.55,800).
Slope m=%281600-800%29%2F%280.15-0.55%29
m=800%2F0.40
m=2000
Using point-slope form for a line, and the lower-y point,
y-800=2000%28x-2.55%29
highlight%28y=2000%28x-2.55%29%2B800%29

Answer: 108.75 inches or 9.0625 ft</h3>
This is equivalent to 9 ft + 0.75 of an inch, or 9 ft + 3/4 of an inch
==========================================================
Work Shown:
7 & 1/4 = 7.25
Each riser is 7.25 inches tall
15 of them gives a total height of 15*7.25 = 108.75 inches
Divide that by 12 to convert to feet
108.75/12 = 9.0625 feet
9.0625 ft = 9 ft + 0.0625 ft
9.0625 ft = 9 ft + (0.0625 ft)*(12 inches/1 ft)
9.0625 ft = 9 ft + 0.75 inches
9.0625 ft = 9 ft + 3/4 of an inch
