400 meters is standard lap distance for a race track. 2 x 50 meters is lap distance in International pools. A lap of 440 yards is 1/4 mile. So 4 laps/mile.
The population parameters that describe the y-intercept and slope of the line relating y and x are β₀ and β₁ respectively.
<h3>What is a
population model?</h3>
A population model can be represented by the equation:

Where μy is the population mean, β₀ is the y intercept and β₁ is the slope of the line
The population parameters that describe the y-intercept and slope of the line relating y and x are β₀ and β₁ respectively.
