The average number of pair of shoes is 30.35.

Explanation of Solution

Given Information:

Selected female student from their school is 20.

The data is:

50	26	26	31	57	19	24	22	23	38
13	50	13	34	23	30	49	13	15	51

Formula Used:

The average formula is:

Average $\left(\text{<mover accent="true"><mo>x</mo><mo>¯</mo></mover>}\right)\text{=}\frac{\text{Sum}\text{of}\text{the}\text{terms}}{\text{Number}\text{of}\text{the}\text{terms}}$

Calculation:

The data recorded for number of shoes of female student.

50	26	26	31	57	19	24	22	23	38
13	50	13	34	23	30	49	13	15	51

To find the average number of pairs of shoes, use average formula.

  $\overline{x}=\frac{50+26+26+\cdots +13+15+51}{20}=30.35$

Hence, the average number of pair of shoes is 30.35.
