Question

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

Answer 1

Answer:

44 swimmers

Step-by-step explanation:

Answer 2

When the temperature is 88 degrees Fahrenheit, the number of swimmers will be 117 at the pool.

What is a regression equation?

In statistics, a regression equation is used to determine whether or not there is a link between two sets of data. It's the regression lines' algebraic expression. It's used to forecast the dependent variable's values based on the values of the independent variables.

How to solve this problem?

Here, the regression equation is

y = 1.5045x - 88.206, where x represents the temperature and y represents the corresponding number of swimmers

Given that x = 88. We have to find the corresponding y value.

Now, y = 1.5045*88 - 88.206

i.e. y = 132.396 - 88.206 = 44.19

Since the nearest whole number is 44, so we can conclude that the number of swimmers is 44.

Therefore, when the temperature is 88 degrees Fahrenheit, the number of swimmers will be 44 at the pool.
