Answer 15

that worked....

I can draw the box and whisker plot, but I do not know about the equation that best fits.

Q2 (median) = 17.2
Q1 = 11.3
Q3 = 25.4
min number = 4.4
max number = 31.3

thats the box and whisker plot.
As far as the line of best fit....I guess you can make a graph where the y axis is the age and the x axis is the weight...then plot your points and find the line that best fits...but I am not too good at that.
