Answer 2

Answer:

Step-by-step explanation:

let the temperature of this month in last 20 days are 22, 24, 20,21,22,25,22,19,18 ,19,21,18,18,19,21,22,24,18,20,24 .these all are temperature in forenhite.

1- range= max value- min value

=25-18=7

2-mean= sum of all data/ total no. of data

=417/20=20.85

distance from mean = mean- value

so the distance are 1.15,3.15,0.85,0.15,1.15,4.15,1.15,1.85,2.85,1.85,0.15,2.85,2.85,1.85,.15,1.15,3.15,,2.85,3.85,2.85,0.85,3.15

mean deviation= sum of all distance/ total no. of terms

=41.15/20

=2.0575

by using this data you can easily draw the data.

all the data are taken in this question are not real. please use your data.
