answer to a is zero
Problem 4 Refer to the box plots in Problem 3. : 4.0 points Compare experiments 4 and 5. When drawn on the same scale, the histogram for one of them has a noticeably higher peak the histogram for the other. From the box plots alone, can you tell which one has the higher peak? ...
Problem 3 John Tukey, the mathematician who came up with the idea of the stem and leaf plot, developed several other methods that were brilliant combinations of simplicity and effectiveness. One such is the box plot, also known as a box and whisker plot. It is, not surprisingl...
Problem 2 Here is another distribution you have seen before; it is the distribution of scores discussed in Lecture 2.1. 4|8 5|9 6|3337 7|0002355 8|01234788 9|015556 10|0 : 6.0 points Each part is worth 2 points. a) Use the stem and leaf plot to find the 20th percentile: unansw...
Problem 7 Refer again to the table in Problem 6. : 3.0 points Fill in the value of the missing entry.
Problem 6 A histogram shows the number of hours students spent preparing for a test. The table below gives the intervals and the heights of the bars (in percent per hour). Intervals contain the left endpoint but not the right. No student spent 25 hours or more in preparation. ...
10 percent per centimeter
Problem 5 In a histogram of lengths measured in millimeters, the height of the 20-40 bar is 1 percent per millimeter. If I measure all the lengths in centimeters instead, then the corresponding bar would be labeled 2-4. : 5.0 points The height of this bar would be: 1 percent p...
Problem 4 Refer again to the distribution table in Problem 3. : 3.0 points Each part is worth 1 point. a) In the United States, high school diplomas are awarded after 12 years of schooling. Which interval contains the adults who had completed 12 years of school and did not pro...
