Question

enter values for x and y in the table to plot points in the graph.
the data points represent the number of swimmers at
city pool compared to the outside temperature.
(66,8),(71,23),(72,16),(75,30),(78,35),(80,24),
(82,37),(86,37),(87,42),(90,50)
use the regression equation to determine how many
swimmers will be at the pool when the temperature is
88°f? round to the nearest whole number.
swimmers

Explanation:

Step1: Input the data into a regression calculator

Input the data points \((66,8),(71,23),(72,16),(75,30),(78,35),(80,24),(82,37),(86,37),(87,42),(90,50)\) into a regression calculator.

Step2: Obtain the regression equation

The regression equation is \(y = 1.53x - 93.79\) (where \(x\) is the temperature and \(y\) is the number of swimmers).

Step3: Substitute \(x = 88\) into the regression equation

Substitute \(x = 88\) into \(y=1.53x - 93.79\).

Step4: Round the result

Round \(40.85\) to the nearest whole number.

Answer:

\(41\) Swimmers
