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

Accepted Solution

A:
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 = 3Minimum  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.
