Answer with explanation:
Data set Showing number of times seventh period class attended a summer camp since first grade:
3, 1, 0, 4, 1,⇒⇒Mean =1.8
4, 2, 3, 0, 5,⇒⇒Mean =2.8
0, 1 , 1, 2, 0,⇒⇒Mean =0.8
4, 1, 4, 4, 2,⇒⇒Mean =3
3, 2, 0, 1, 4⇒⇒Mean =2
⇒≡Mean of a Data set is sum of all the variate in data set divided by total number of Variate in the data set.
Range of the sample Means of a data set is difference between Maximum value of variate in the data set and Minimum value of Variate in Data set.
Maximum Value in the sample mean = 3
Minimum Value in the sample mean = 0.8
⇒Range = Maximum value of mean - Minimum value of mean
= 3 - 0.8
= 2.2
⇒≡None of the option given, matches with the value of range Calculated.
