Darren wants to estimate the mean age in a population of trees. He'll sample n
nn trees and build a
90
%
90%90, percent confidence interval for the mean age. He doesn't want the margin of error to exceed
3
33 years. Preliminary data suggests that the standard deviation for the ages of trees in this population is
σ
=
16
σ=16sigma, equals, 16 years.

Formulate the indicated conclusion in nontechnical terms. be sure to address the original claim. the foundation chair for a hospital claims that the mean number of filled overnight beds is over 523, and she is therefore justified starting a funding campaign to add a wing to the hospital. assuming that a hypothesis test has been conducted and that the conclusion is failure to reject the null hypothesis, state the conclusion in nontechnical terms.

Abc is dilated by a scale factor of 3 with the origin as the center of dilation, resulting in the image a'b'c'. if the slope of line ab is -1.2, what is the slope of line a'b'? a. -1.2b. 3.6c. 1.2d 1.8
