Question

Based on the equation for line of best fit: ŷ=−20.65−56.98x If the value for x is controlled to be 110 units, what will be the estimated value of y?

Answer 1

The estimated value is -6288.45.

Explanation:

Consider the provided equation.

`\hat y=-20.65-56.98x`

We need to find the value of
`\hat y` if the value for x is 110.

Substitute x = 110 in the provided equation.

`\hat y=-20.65-56.98(110)`

`\hat y=-20.65-6267.8`

`\hat y=-6288.45`

Hence, the estimated value is -6288.45.
