dima asked her seventh-period class how many times they attended a summer camp since first grade. she put her data in the table and used the shaded rows to find sample means. summer camp attendance
3 1 0 4 1
4 2 3 0 5
0 1 1 2 0
4 1 4 4 2
3 2 0 1 4
what is the range of the values for the sample means?
1
1.2
1.8
2

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.
