What are the values of the median and the mean of this distribution?{1, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 5, 6, 7}
PSYCHO15rus [73]
The median( middle number), and if there is an even amount of numbers (which is what there is in this problem, there will be 2 middle numbers.....so u take the 2 middle numbers...add them and divide by 2 to find the median.
(3 + 3) / 2 = 6/2 = 3....median is 3
the mean (average) can be found by adding up all the numbers and dividing by how many numbers there are. 55/16 = 3.4275 rounds to 3.43 <== mean

Answer: Choice B</h3>
Positive, because the products (-5)(-3) and (-8)(-6) are positive, and the product of two positive numbers is positive
=======================================================
Explanation:
Recall we have these rules
- positive times positive = positive
- positive times negative = negative
- negative times negative = positive
Here is one example for each rule
- 8*7 = 56
- 5*(-9) = -45
- -2*(-4) = 8
So based on that, we know that (-5)(-3) is positive. The two negatives cancel each other out so to speak. The same goes for (-8)(-6). Then multiplying any two positive numbers produces another positive outcome.
