the back-to-back stem-and-leaf plot below shows the ages of patients seen by two doctors in a family clinic one day. what is the difference between the age of the oldest patient seen by doctor 1.

I don't get it....

I'm sorry no one helped you. Here's what I got:

Doctor 1 - mean: 12 median: 12
Doctor 2 - mean: 14 median: 18.5

The only thing I don't understand is, how are we supposed to compare the two? Hope I helped you in some way.

Ms. Sue, you didn't even help the poor guy (or girl?). To compare, you have to find the range between the two. The range is 6 years.

answers for connexus students are:

1.a
2.c
3.d
4.c
5.d
6.d
7.c
8.you'll have to figure out on your own :)

Your welcome, 100% guaranteed!!

and doctor 2 using the mean and median of each data set

which is
doctor 1 doctor 2
|3|5
920|2|00236
875|1|37
973211|0|2239
Key: means 29 <---9|2|3--->means 23

The median is the value in the middle of the data set when the numbers are arranged from least to greatest. The numbers in the data set for #8 were not organized, so you wouldn't add / divide 20 + 16. ^^

To find the median, you would need to rearrange the numbers for both data sets (As state above):
(Doctor 1) 1+1+2+3+7+9+15+17+18+20+22+29+32
(Doctor 2) 2+3+9+13+15+17+20+22+23+26+35

So actually, the median would be 15 for doctor 1 and The median for Doctor 2 is 32 (the median is the mean of 15 and 17. 15+17/2 = 32.)
Hope this helps, ciao :)

If you don't understand #8, try to look back at your last question and explain how you got that or something

#7 is C

can someone please explain how to do this.... and possibly an example or 2
