Review Learning Goal: To use the principle of work and energy to determine characteristics of a mass being pulled up an incline and determine the power that must be supplied to the system when the efficiency of the input system is considered. As shown, a 63 kg crate is pulled up a $\theta = 50^\circ$ incline by a pulley and motor system. Initially at rest, the crate is pulled $s = 5.1$ m up along the incline. Undergoing constant acceleration, the crate reaches a speed of 2.6 m/s at the instant it has traveled this distance. (Figure 1) Considering the coefficient of kinetic friction, $\mu_k = 0.15$, determine the power that the motor must supply to the crate the instant the crate travels a distance of 5.1 m. Express your answer to two significant figures and include the appropriate units. View Available Hint(s) P = Value Units Submit Part B - Power supplied to the motor when efficiency is considered If the motor has an efficiency of $\epsilon = 0.86$, what power must be supplied to the motor to raise the crate? Express your answer to two significant figures and include the appropriate units. View Available Hint(s) P = Value Units Figure 1 of 1 >>

CHAPTER 8. INTRODUCTION TO LINEAR REGRESSION 8.37 Murders and poverty, Part II. Exercise 8.25 presents regression output from a model for predicting annual murders per million from percentage living in poverty based on a random sample of 20 metropolitan areas. The model output is also provided below. Estimate Std. Error t value Pr(>|t|) (Intercept) -29.901 7.789 -3.839 0.001 poverty% 2.559 0.390 6.562 0.000 s = 5.512 R2 = 70.52% Radi = 68.89% (a) What are the hypotheses for evaluating whether poverty percentage is a significant predictor of murder rate? (b) State the conclusion of the hypothesis test from part (a) in context of the data. (c) Calculate a 95% confidence interval for the slope of poverty percentage, and interpret it in context of the data. (d) Do your results from the hypothesis test and the confidence interval agree?
