Explanation:

First Dataset: 14, 15, 10, 11, 5

Step1: Sum the numbers

$14 + 15 + 10 + 11 + 5 = 55$

Step2: Divide by the count (5)

$\frac{55}{5} = 11$

Step1: Sum the numbers

$13 + 4 + 13 = 30$

Step2: Divide by the count (3)

$\frac{30}{3} = 10$

Step1: Sum the numbers

$30 + 35 + 23 + 61 + 1 = 150$

Step2: Divide by the count (5)

$\frac{150}{5} = 30$

Answer:
