Question

starting with the values 70 and 100, add 3 data values to the sample so that the mean is 76. the median is 82 and the mode is 82. show work

Answer 1

70+82+82+100+x/5=76
(There has to be at least two 82's since it is the mode.) Solve for x, and that's the third unknown.

Answer 2

starting with the values 70 and 100, add 3 data values to the sample so that the mean is 76. the median is 82 and the mode is 82. show work. (please help me find the 3 data values and show how was figured out. i am totally confused.

Answer 3

I did explain it, Mary. We already know that you have a 70 and 100. There has to be at least 82's since it's the mode (occurs the most). We can then solve for the missing number. (70+82+82+100+x)/5=76..x will be the last missing number.

Answer 4

70+83+83+x+100/5=76

336+x=5(76)

380-336=44

x=44 which is the third number therefore the number group will be

70+83+83+44+100
