Stem and leaf plot need help

1)38.5

2)39

Step-by-step explanation:

median: put the numbers smallest to biggest the cross out the number from both sides one by one until you get to the middle if there are two numbers in the  middle the add them and divide it by 2

mean: add them all up and then divide by how many numbers there are in total

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
