Question

The daily minimum temperatures in degrees Ce1siu& 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 the first class
interval.

Answer 1

Since the first class is –19.9 to –15

Therefore, the frequency distribution in which the lower limit is included and upper limit excluded is:

Temperature	Tally marks	Frequency
-19⋅9 to -15	||	2
-15 to 10⋅1	||| ||||	7
-10⋅1 to -5⋅2	|||||	5
-5⋅2 to -0⋅3	||||	4
-0⋅3 to -4⋅6	||||| ||||| ||||| ||	17
