Answer 2

___ ___ ___ ___ ___ ___ ___

start by making 7 blanks and then filling in the appropriate information from the problem

for Jones ---> min = 65, median = 74, mean = 75, mode = 76. we can start by filling in the median and min

65 ___ ___ 74 ___ ___ ___

76 is the mode, so 76 must appear at least twice

65 ___ ___ 74 76 76 ___

in general the sum of a set of numbers is (mean)(# of numbers in the set)

so for Jones, the sum is 7*75

so you just have to fill in the rest of the numbers to get a sum of 7*75

Answer 5

yeah that's pretty much how I have it set up too

using 65,j,j74, 76, 76,j, I did a bit of trial-and error

I want the first 2 j values to be in between 65 and 74 so the last j value has to be pretty high, so i chose 90

65, j, j, 74, 76, 76, 90 ----> sum = 7*75

the missing 2 j values have to add up to 144 (7*75 - all the other values), so you could pick 71 and 73 and that would satisfy all the conditions

65, 71, 73, 74, 76, 76, 90

Answer 6

you have the right setup, you just have to do a bit of trial-and-error to find the right data points
