Answer 1

3,4,4,5,7,8,15,15,17

is bimodal with two modes: 4 and 15

median =the middle number: 8

put the numbers in order, there are 9 numbers

the middle number is the one with 4 lower and 4 higher

if the total number were even, such as for example: 10

then take the average of the 2 middle numbers, the 5th and 6th

largest numbers

range = max-min = 17-3 = 14

mean = sum divided by the number of numbers

= 78/9= 8 2/3

= 8.666...

= 8.67 rounded to 2 decimal places
