Robert says his better long jump was about 1 foot farther than may's better long up. is he correct? explain.

So he is wrong

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  

Mays jumps : 4 2/3 and 4 3/4

Robert jumps : 6 1/12 and 5 2/3

My

May:

=> May better jump is: 4.75 feet

Robert:

=> Robert better jump is: 6.08  feet

The difference between Robert's better long jump and May's better long jump is:

6.08  -   4.75 = 1.33 feet

So he is wrong, it is 1.33 feet not 1 foot

y=mx+b

step-by-step explanation:

m slope, b y-intercept

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17
