we have
1 donut -----> 570 calories
7 donuts ----> 600 calories
7 donuts ----> 510 calories
4 donuts ----> 480 calories
3 donuts ----> 400 calories
so
total donuts=1+7+7+4+3=22 donuts
the means is equal to
mean=(1*700+7*600+7*510+4*480+3*300)/22
mean=11,460/22
<h2>mean=521 calories</h2>
Part 2
Find out the median
order the data set from less to greater
400 400 400 480 480 480 480 510 510 510 510 510 510 510 570 600 600 600 600 600 600 600
the median is the middle of the data set
400 400 400 480 480 480 480 510 510 510 510 510 510 510 570 600 600 600 600 600 600 600
<h2>the median is 510 calories</h2>
