The daily maximum temperature recorded in a certain city during the month of November are as follows: 24.5, 25.8, 25.6, 20.7, 21.8,20.5,20.6,20.9,23.1,22.4,21.5,22.7,22.8,22.0,23.9,22.8,23.8,24.6,21.1,23.9 Represent them as a frequency distribution table with class size 1^@C .

Given below are the ages of 40 people in a colony: {:(33,8,7,28,30,25,6,50,24,44),(56,32,27,21,17,62,58,16,14,19),(24,31,27,5,12,46,15,42,67,34),(4,21,10,40,20,50,48,63,9,21):} Taking class intervals 1-10, 11-20, 21-30, 31-40, 41-50, 51-60 and 61-70, we construct a frequency distribution table for th above data.

Given below are the ages of 45 people in a colony. {:(33,8,7,25,31,26,5,50,25,48,56),(33,28,22,15,62,59,16,14,19,24,35),(26,9,12,46,15,42,63,32,5,22,11),(42,23,52,58,62,10,24,43,51,37,48):} 36 Construct grouped frequency distribution for the given data with 6 class intervals.

Find the median of the data 30,25,32,23,42,36,40,33,21,43.

Verify that (3,4,5),(5,12,13),(8,15,17),(24,25,7) are the Pythagorean triplets
