Answer #1

Solution:
Total number of values or frequency = 30 + 66 + 43 + 20 + 10 = 169
Relative frequency can be calculated as
Relative frequency for Number of Class limits = Frequency of respective Number of days class limits/Total frequency
Relative frequency for 0 to 5 = 30/169 = 0.178
Relative frequency for 6 to 11 = 66/169 = 0.391
Relative frequency for 12 to 17 = 43/169 = 0.254
Relative frequecny for 18 to 23 = 20/169 = 0.118
Relative frequency for 24 to 29 = 10/169 = 0.059
Percentage for 0 to 5 = 0.178 * 100% = 17.8%
Percentage for 6 to 11 = 0.391*100% = 39.1%
Percentage for 12 to 17 = 0.254*100% = 25.4%
Percentage for 18 to 23 = 0.118*100% = 11.8%
Percentage for 24 to 29 = 0.059*100% = 5.9%

Number of Days Class limits Frequency Relative frequency Percentage
0 to 5 30 0.178 17.8
6 to 11 66 0.391 39.1
12 to 17 43 0.254 25.4
18 to 23 20 0.118 11.8
24 to 29 10 0.059 5.9
