c. 10, 10, 10, 15, 20
d. 1, 2, 3, 2, 2

Explanation:

Step1: Calculate mean for Set A

$\text{Mean}_A = \frac{10 + 15 + 15 + 15 + 20}{5} = \frac{75}{5} = 15$

Step2: Calculate mean for Set B

$\text{Mean}_B = \frac{7 + 8 + 10 + 12 + 13}{5} = \frac{50}{5} = 10$

Step3: Calculate mean for Set C

$\text{Mean}_C = \frac{10 + 10 + 10 + 15 + 20}{5} = \frac{65}{5} = 13$

Step4: Calculate mean for Set D

$\text{Mean}_D = \frac{1 + 2 + 3 + 2 + 2}{5} = \frac{10}{5} = 2$

Answer:

B. 7, 8, 10, 12, 13
