Answer:

7.1 miles

Step-by-step explanation:

From the park to the library is a diagonal line. We can use pythagorean theorem.

Change in y - 7

Change in x - 1

7^2 + 1^2 = x^2

(x is the distance between the library and park)

49 + 1 = x^2

50 = x^2

That's around 7.

A certain statistic bˆ is being used to estimate a population parameter B. The expected value of bˆ is equal to B. What property

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
