The plots below were created using the Galton data set from the mosaic package. For each, provide R code that will create the plot. (Do not customize colors or labels or do other fancy things; just give the code to make the basic plot exactly as shown.)

When creating the dot plot, how are multiple data points for a single score displayed? a. A larger size dot is used; the size of the dot is directly proportional to the number of data points. b. More than one dot is used; dots are placed side by side creating a wider interval. c. A dot plot is innappropriate when multiple data points exist for a single score. d. Multiple dots, representing each data point, are replaced on top of one another.

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?
