Question

The daily minimum temperatures in degrees celsius recorded in a certain Arctic region are as follows:

-12.5, -10.8, -18.6, -8.4, 10.8, -4.2, -4.8, -6.7, -13.2, - 11.8,

-2.3, 1.2, 2.6, 0, 2.4, 0, 3.2, 2.7, 3.4, 0,

-2.4, -2.4, 0, 3.2, 2.7, 3.4, 0, -2.4, -5.8, -8.9,

-14.6, -12.3, - 11.5, -7.8, - 2.9.

Represent them as frequency distribution table taking - 19.9 to -15 as one of the class interval

Solution

Minimum temperature = - 18.6
Maximum emperature = 3.4
Range = 3.4 - (-18.6) = 3.4 + 18.6 = 22

The required frequency distribution table is given below:
