The class having maximum frequency is the modal class. The maximum frequency is 20 and hence the modal class = 40-50 Lower limit (l) of modal class = 40, class size (h) = 10 Frequency ( ) of the modal class = 20 frequency ( ) of class preceding the modal class = 12, frequency ( ) of class succeeding the modal class = 11 Thus, Mode of the data is 44.70

The class having maximum frequency is the modal class. The maximum frequency is 18 and hence the modal class = 4000-5000 Lower limit (l) of modal class = 4000, class size (h) = 1000 Frequency ( ) of the modal class = 18 frequency ( ) of class preceding the modal class = 4, frequency ( ) of class succeeding the modal class = 9 Thus, Mode of the data is 4608.70

The class having maximum frequency is the modal class. The maximum frequency is 10 and hence the modal class = 30-35 Lower limit (l) of modal class = 30, class size (h) = 5 Frequency ( ) of the modal class = 10 frequency ( ) of class preceding the modal class = 9, frequency ( ) of class succeeding the modal class = 3 Thus, Mode of the data is 30.625 Now, Let the assumed mean be a =...

The class having maximum frequency is the modal class. The maximum frequency is 40 and hence the modal class = 1500-2000 Lower limit (l) of modal class = 1500, class size (h) = 500 Frequency ( ) of the modal class = 40 frequency ( ) of class preceding the modal class = 24, frequency ( ) of class succeeding the modal class = 33. Thus, Mode of the data is Rs. 1847.82 Now, Let the assumed...

The class having maximum frequency is the modal class. The maximum frequency is 61 and hence the modal class = 60-80 Lower limit (l) of modal class = 60, class size (h) = 20 Frequency ( ) of the modal class = 61 frequency ( ) of class preceding the modal class = 52, frequency ( ) of class succeeding the modal class = 38. Thus, the modal lifetime of 225 electrical components is 65.62 hours
