Answer:

The answer is No, the results are likely to occur by chance.

Step-by-step explanation:

On his way to work, a man notices that 9 of the 16 traffic lights are green. Is there statistical significance to say that these traffic lights are programmed to allow ease of travel:

<em>The answer is No, because the results are likely to occur by chance.</em>

As the number of green and non-green lights are approximately the same so we can't judge anything regarding the ease to travel.

What is the mean median mode and range of the numbers 31 28 30 31 30 ...?
mamaluj [8]
1. Mean is the number you get when you add all these numbers and then divide by the number of numbers. So, (31 + 28 + 30 + 31 + 30) / 5 = 150 / 5 = 30
2. The median is the middle number in the list of numbers, so, the answer is 30 as well.
3. Mode is the number that appears most often, so here it is 30 and 31 because they both appear 2 times.
4. Range is the difference between the largest and smallest number, so 31 - 28 = 3.

Here are the percents of the popular
Murljashka [212]

Answer:

Ok, you should first order every number in the regular order (1,2,3,4,5,6,7,and so on) or (1.2,1.3,2.4,5.9).

43.2, 43.4, 47.9, 49.2, 49.6, 49.7, 50.1, 50.7, 51.2, 53.9, 55.1, 57.4, 58.8, 60.7, 61.1.

Median means the exact middle and here there are total of 15 different numbers so we know this is going to be easier if this was even. 50.7 is the median because it is in the middle and there are an even number of numbers on each side to it, 7.
