Arborists are often interested in developing procedures that will allow them to accurately measure trees without subjecting themselves to danger. Suppose an arborist collects sample of trees and measures the height (ft ) and circumference (ft ) of each. The following data resulted: Height Circumference (ft) (ft) 1Assuming we meet all necessary assumptions, is our sample correlation coefficient of a sufficient magnitud: to indicate that; in the population of trees circumference and height are cor

Arborists are often interested in developing procedures that will allow them to accurately measure trees without subjecting themselves to danger. Suppose an arborist collects sample of trees and measures the height (ft ) and circumference (ft ) of each. The following data resulted: Height Circumference (ft) (ft) 1 Assuming we meet all necessary assumptions, is our sample correlation coefficient of a sufficient magnitud: to indicate that; in the population of trees circumference and height are correlated? Answer this question by conducting formal hypothesis test using an 0.05 significance level: Assume that the mean circumference is 5.429 the standard deviation for the circumference is 2.992, the mean height is 45.571 , and the standard deviation for the height is 19.823, and 0.9281 _ What is the null hypothesis for this test?

One experimental method of measuring an insulating material's thermal conductivity is to construct a box of the material and measure the power input to an electric heater inside the box that maintains the interior at a measured temperature above the outside surface. Suppose that in such an apparatus a power input of 180 W is required to keep the interior surface of the box 65.0 C$^\circ$ (about 120 F$^\circ$) above the temperature of the outer surface. The total area of the box is 2.18 m\$^2
