- QUESTION 4 In an effort to reduce energy costs, a major university has installed more efficient lights as well as automatic sensors that turn the lights off when no movement is present in a room. Historically, the cost of lighting an average classroom for 1 week has been $265. To determine whether the changes have signficantly reduced costs, the university takes a sample of 50 classrooms. They find that the average cost for 1 week is $247 with a standard deviation of $60. When testing the hypothesis (at the 5% level of significance) that the average energy use has decreased from the past, what is your conclusion concerning the null hypothesis? Reject the null hypothesis Fail to reject the null hypothesisarrow_forwardQUESTION 2 In an effort to reduce energy costs, a major university has installed more efficient lights as well as automatic sensors that turn the lights off when no movement is present in a room.

- Question 4 Listen Your Algebra 2 teacher collected data on the number of days each student was absent during a semester and their score, in percent, on the semester exam. The linear regression equation that models the data is ŷ=97.769-3.828x where x represents the number of days absent and y represents the exam score, in percent. The correlation coefficient is r=-0.707 and the coefficient of determination is =0.500. What are the appropriate interpretations of the slope, y-intercept, correlation coefficient, and coefficient of determination? **HINT** Slope: -3.828 y-intercept: 97.769 Correlation coefficient: r = -0.707 The rate the predicted semester exam score decreases for every stu- dent absence. The predicted % score a student will achieve based on having zero absences in a semester. a. correlation coefficient b. y-intercept c. slope The relationship be- tween the number of days a student was ab- sent and their corre- sponding exam score.arrow_forwardQuestion 8 Central Perk orders their organic coffee filters from a South American supplier that mails them as inexpensively (hence, as slowly) as possible.
