Time (sec) frequency 60 to 119 8 120 to 179 25 180 to 239 14 240 to 299 2 300 to 359 6 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?

We are given the below frequency table:

Time (sec)    Frequency

60 to 119                    8

120 to 179            25

180 to 239            14

240 to 299             2

300 to 359             6

Total                           55

Therefore, there are 55 individuals included in the summary.

Is it possible to identify the exact values of all of the original service​ times?

No, it is possible to identify the exact values of all of the original service times because the data values in each class could take on any value between the class​ limits,                  

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
