difference between room air temperature and the air at the pool's surface. Data were collected from a wide range of pools where the evaporation level was known. The new formula was applied to each pool in the sample, yielding an estimated evaporation level. The absolute value of the deviation between the actual and estimated evaporation level was then recorded as a percentage. The researchers reported the following summary statistics for absolute de- viation percentage: = 18, s ple containedn = 500 swimming pools. a. Estimate the true mean absolute deviation percentage 20. Assume that the sam- %3D %3D for the new formula with a 90% confidence interval. b. The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) handbook also provides a formula for estimating pool evapora- tion. Suppose the ASHRAE mean absolute deviation percentage is u = 34%. (This value was reported in the article.) On average, is the new formula “better" than. the ASHRAE formula? Explain. %3D

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
