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

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

Temperature    Calculate of Cars Speeding
50                   10
65   12
80   16
85   16
90   13
70   10
75   12
25. Use  the arrangement of retrogradation dissection to experiment the relation among  temperature (X) and the calculate of cars reordered as speeding (Y). Set  __=.05
