Let p be the profit (in millions of dollars) of a company for the year that is t years since 2000. Some pairs of values of t and p are shown in the following table. a. Create a scattergram of the data. Then draw a linear model. Choose the correct scattergram below. (millions of dollars) 36 (years) A. O B. AP 40- 1 AP 40- 32 per 28 20 6. 16 teg 0- 10 10 Complete parts a. to d C. D. AP 40- Ap 40- ng 0- 10 10 b. Predict when the profit will be $4 million. The profit will be $4 million in the year c.

Twenty five right-handed students were asked to turn a knob (using their right hands) that moved an indicator by screw action. There were two identical instruments, one with a right-hand thread (the knob turns clockwise) and the other with a left-hand thread (the knob turns counterclockwise). The data presented below gives the times (in seconds) each subject took to move the indicator a fixed distance: Obs.# R Obs.# R L L Obs.# R 1 113 8 116 166 22 100 2 105 105 9 75 146 23 89 3 130 133 10 96 123 24 85 4 101 108 11 122 135 25 88 5 138 115 12 103 6 118 170 13 116 7 87 103 14 107 At 1% level of significance, can we conclude that these right-handed students found it easier to use the knobs with a right-hand thread? Use the following form of the difference: right-left. 1. Test Stat: L 137 2. Critical Region: a. T> 2.492 b. Tabs (2.492) c. T> abs (-2.492) d.
