Answer:

Hadley's car.

Step-by-step explanation:

√120 is less than 15. 11 times 11 is 121 which is already less than 15.

Sorry if it isn't explained that well

Answer:

Hadley's car is longer.

Step-by-step explanation:

Ephraim's car is √120 feet long. Hadley's car is 15ft long.

we know $\sqrt{121} \ is \ 11$

$\sqrt{100} \ is \ 10$

$\sqrt{120} \ lies \ between \ \sqrt{100} \ and \ \sqrt{121}$

So $\sqrt{120}$ is close to 11

Ephraim's car is approximately 11 feet long

Hadley's car is 15ft long.

15 feet is the longer

Hadley's car is longer.

insens350 [35]

Answer:

Unbiased

Step-by-step explanation:

If b^ is equal to B this means that it is an unbiased estimator. When there is an absence of bias, we have an unbiased estimator. As an unbiased estimator it gives accurate information most of the time. The result it gives is not over estimated and also it is not underestimated.

Expected value = true value

Parameter estimates are correct on average
