In a neighborhood donut shop, one type of donut has 570 calories, seven types of donuts have 600 calories, seven types of donuts have 510 calories, four types of donuts have 480 calories, and three types of donuts have 400 calories.Find the mean number of calories in these donuts. Round your answer to the nearest whole number, if necessary. caloriesFind the median number of calories in these donuts. calories

Answer 1

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

mean=521 calories

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

the median is 510 calories
