Answer 1

Anso- Note :- Frequency distribution, relative frequency, cumulative Relative frequency ie a, b, c. are in One table only shown below Rating Frequency | Relative Frequency 15/60 0.25 Cumulative Relative Frequency 0.25 Excellent (E) Good (G) 26 26/60 = 0.433 0•683 Fair (F) 1%0700167 0.85 Poor (P) 9 %0= 0.15 Total From above data d) horizontal bar chart 126 15 0 10 20 30 40 Answer is Option (B)

e) What percentage of Customers either Excellent or Good rated ar Relative Frequency of excellent + Relative frequency of Good) x 100% = (0:25+0.433) X 100% (0.683) X 100% = 68.3% & Customers rated either Excellent or Good = 68.3%
