Answer

Explanation:

Step1: Calculate the sum of products

First, find the product of each sum - frequency pair and then sum them up. [ (5\times1)+(7\times2)+(9\times3)+(11\times4)+(13\times3)+(15\times2)+(17\times1)=5 + 14+27 + 44+39+30+17=176]

Step2: Calculate the total frequency

Sum up all the frequencies. [1 + 2+3 + 4+3+2+1=16]

Step3: Calculate the mean

Divide the sum of products by the total frequency. [ \text{Mean}=\frac{176}{16}=11]

Step4: Find the median

Arrange the data in ascending - order of sums with their frequencies. There are 16 data points. The median is the average of the 8th and 9th ordered data - points. The first (1 + 2+3=6) data - points have sums less than 11, and the first (1 + 2+3 + 4 = 10) data - points have sums of 11 or less. So, the 8th and 9th data - points are 11, and the median is 11.

Step5: Find the range

The range is the difference between the maximum and minimum values. The maximum sum is 17 and the minimum sum is 5. So, the range is (17 - 5=12).

Answer:

The mean is the same as the median.
