Following table shows children age 1 to six years of age

Age in years 1,2,3,4,5,6
1=14
2=16
3=8
4= 8
5= 6
6= 3

(I) find the total number of children age 1 to 6 living on the road

(II) how many children are aged two or less

(III) what percentage of children are age 3 and over?

(IV) calculate the mean of the distribution

(v) what is the mode of the distribution

I will be so grateful if anybody can answer this correctly for me

For any item 5 pounds or greater, the following equation gives the price, p(w), of shipping the item between two locations as a function of the item's weight, w, in pounds. Then, the equation is for w>=5 (pounds).

The company does not use the following equation to determine shipping prices for items which are greater than 80 pounds. Then, the equation is used for
w<=80 (pounds)

The domain of p(w) is the values we can give to w, then
Domain of p(w) is 5<=w<=80
Domain of p(w) = [5, 80]

Domain of p(w) = [5, 80]
