Passage

There is a proverb: "Cleanliness is next to godliness." If we keep our bodies clean, we can guard against germs, bacteria, and viruses. The spray of insecticides can destroy insects like flies, mosquitoes, and bugs etc. The parks and other public places have become dirty because we neglect cleanliness. The black granules of smoke cause another threat to the cleanliness of our homes. Cleanliness is the first step to reach Heaven. If we become sincerely serious and want to get rid of many diseases, we will have to keep clean not only our body, our surroundings but also our inner thoughts.

It is a fact that the change takes place in our inner self, but the tragedy is that we have many skins covering the depths of our inner self. We know so many things, but do not know ourselves.

To find the weighted mean:

Step 1: Calculate the weighted sum

Weighted sum = (18_2) + (19_3) + (20_4) + (21_2) + (22_1) + (23_1) + (24*1)

= 36 + 57 + 80 + 42 + 22 + 23 + 24

= 284

Step 2: Calculate the total weight

Total weight = 2 + 3 + 4 + 2 + 1 + 1 + 1

= 14

Step 3: Calculate the weighted mean

Weighted mean = Weighted sum / Total weight

= 284 / 14

= 20.286
