Questions 21-24 appeal to the aftercited situation:

On his early equalize, a researcher notices that the shorter the gap of era among commerce digestible changes, the balance vehicles run the red light. Interested in this relation, the researcher conducts an experiment balance the instant few weeks. Each early he leading chooses a commerce digestible at vague. Once the digestible changes, he begins reckoning the calculate of vehicles ordinary red digestibles. He continues to reckon until the digestible changes intermittently. The basis on six digestibles is as follows:

Length of Digestible (X) Calculate of Cars (Y)

10 20

13 19

19 17

25 11

28 9

30 8

21. Calculate the retrogradation arrangement.

22. What is the Y-intercept?

23. Calculate the coefficient of preference.

24. "If the elongation of a digestible was 7 seconds, how divers cars would you forebode would run the red digestible?"

Use the aftercited scenario for 25 singly.

Use the arrangement of retrogradation dissection to experiment the relation among temperature (X) and the calculate of cars narrative as speeding (Y). Set α = .05
