To model some data, Anne ran a linear regression and found the regression equation to be y=0.554x-0.507.
k0ka [10]

Answer:

See Explanation

Step-by-step explanation:

Given

y = 0.554x - 0.507

The question is incomplete; however, a possible question could be to interpret the given equation.

The equation is given in slope intercept form i.e. y = mx + b

Where

m = slope

b = y\ intercept

So, by comparing:

y = mx + b to y = 0.554x - 0.507

m = 0.554

b = -0.507

<em>Hence, the slope of the regression is 0.554 and the y intercept of -0.507</em>

<em>The number or hours Mike works at Sea World in June and the amount of money he will earn on his July paycheck.</em>  

The independent variable because the amount of money he makes depends on how much money he earns.
