- Refer to the table summarizing service times (seconds) of dinners at a fast food restaurant. How many individuals are included in the summary? Is it possible to identify the exact values of all of the original service times? Time (sec) 60-119 120-179 180-239 240-299 300-359 55 individuals are included in the summary. (Type a whole number.) Is it possible to identify the exact values of all of the original service times? Frequency 8 22 16 3 6 (…) O A. Yes. The data values in each class are equal to the corresponding class midpoint. O B. Yes. The data values in each class are spread evenly across the full length of the class. O C. No. The frequency distribution tells nothing about the data values that fall below the lowest class limit or above the highest class limit. O D. No. The data values in each class could take on any value between the class limits, inclusive.Problem 6-29 (Algorithmic) The north-south highway system passing through Albany, New York, can accommodate the capacities shown.
