Explanation:

Step1: Sort data set 5A

$8, 12, 30, 37, 50$

Step2: Find median of 5A

Median = 3rd value = $30$

Step3: Sort data set 5B

$30, 35, 35, 35, 50$

Step4: Find median of 5B

Median = 3rd value = $35$

Step5: Sort data set 5C

$35, 37, 37, 37, 39$

Step6: Find median of 5C

Median = 3rd value = $37$

Step7: Sort data set 5D

$30, 30, 30, 37, 85$

Step8: Find median of 5D

Median = 3rd value = $30$

Step9: Sort data set 6A

$50, 100, 100, 200$

Step10: Find median of 6A

Median = $\frac{100+100}{2} = 100$

Step11: Sort data set 6B

$50, 100, 200, 200$

Step12: Find median of 6B

Median = $\frac{100+200}{2} = 150$

Step13: Sort data set 6C

$100, 100, 400, 500$

Step14: Find median of 6C

Median = $\frac{100+400}{2} = 250$

Step15: Sort data set 6D

$100, 200, 400, 500$

Step16: Find median of 6D

Median = $\frac{200+400}{2} = 300$

Step17: Sort data set 7

$30, 30, 35, 40, 45$

Step18: Find median of 7

Median = 3rd value = $35$

Step19: Sort data set 8

$45¢, 45¢, 50¢, 50¢, 75¢$

Step20: Find median of 8

Median = 3rd value = $50¢$
