Final answer:
To figure out which interval has the least data, one needs to observe the histogram. The interval with the shortest bar has the fewest data points. If the smallest time interval is greater than zero, the lines in a figure will not meet as each interval is distinct.
Step-by-step explanation:
To determine the number of data in a given interval, we need to look at the histogram provided. Since each interval has a width of 1, we can note the frequency of the data set by considering the height of the bars corresponding to each interval. Typically, the interval with the shortest bar would have the fewest number of data points.
Regarding part h of your question, without the visual histogram, we cannot say for certain which interval has the fewest data. However, if you look at the histogram, the interval with the fewest data will be the one with the shortest bar. For example, if 38-41 has a shorter bar compared to the others, then it has the fewest number of red sports cars.
For question 11, if the smallest meaningful time interval is greater than zero, the lines in Figure 34.9 would not meet because each interval represents a distinct period that doesn't overlap with the other. Thus, if there's a positive minimum value, there will always be space between the lines, indicating that they will not meet.
