The regression line equation y = 0.502x +12.250 is a linear regression

  • The predicted speed at a drop of 100 feet is 62.45
  • The predicted speed at a drop of 500 feet is 263.25
  • It is unlikely that the speed of the roller coaster would reach 263.25

The predicted speed at a drop of 100 feet

The regression line equation is given as:

y = 0.502x +12.250

Substitute 100 for x

y = 0.502 * 100 +12.250

Evaluate the sum

y = 62.45

The predicted speed at a drop of 500 feet

The regression line equation is given as:

y = 0.502x +12.250

Substitute 500 for x

y = 0.502 * 500 +12.250

Evaluate the sum

y = 263.25

It is unlikely that the speed of the roller coaster would reach 263.25
