Question

Refer to the table summarizing service times (seconds) ofdinners at a fast food restaurant. How many individuals areincluded in the summary? Is it possible to identify the exactvalues of all of the original service times?Time (sec) Frequency60–119 8120–179 25180-239 12240-299 3300-359 6individuals are included in the summary.(Type a whole number.)

Answer 1

of The number of students given in the question with their respective serice times are

To calculate the total number individuals included in the summary we will add up the total frequency

`\begin{gathered} \text{Total individuals } \\ =8+25+12+3+6 \\ =54\text{ individuals} \end{gathered}`

Hence,

54 individuals are included in the summary

Therefore,

No, it is not possible to identify the exact values of all of the original service times in the class limit because it has been separated into different time intervals, so each frequency is just a general number that illustrates the total individuals that fall within each time class interval ( THE VALUES ABOVE ARE GROUPED DATA)

Grouped data are data formed by aggregating individual observations of a variable into groups so that a frequency distribution of these groups serves as a convenient means of summarizing or analyzing the data.
