STATS HELP!! Below are monthly rents paid by 30 students who live off campus:
640 640 640 840 610 500
600 940 650 530 630 595
470 650 560 570 760 830
510 530 670 600 620 410
640 710 730 750 630 655
Mean 637
Median 635
Mode 640
Standard Deviation 112.52

What is the z-score for a rent value of $750?
Are there unusual data values?
Using the Empirical Rule, do you think the data could be from a normal population?

6 on both sides and twelve on the top and the bottom

step-by-step explanation:

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

step-by-step explanation:

because that’s us why

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
