Answer:
Step-by-step explanation:
Hello There!
To find the mean, add up all the numbers and divide according to how many numbers there are. The mean for this set would be <em>"9"</em>
<em></em>
To find the median, place the numbers in value order and find the middle. if there is no middle, add up the two numbers in middle and divide by 2. In this set, the median would be <em>"8.5"</em>
<em></em>
To find the mode or modal value, it is best to put the numbers in order. Then count how many of each number. A number that appears most often is the mode. In this set, there would be no mode.
The range of a set of data is the difference between the highest and lowest values in the set. In this set, the range would be <em>"12"</em>
I rounded each number to the nearest whole number and added those.
29 + 79 + 42 = 150
If you add the original numbers you would get 149.5, which rounds to 150.
The only way to determine whether or not an outcome is unusual or not is to compare it with previous or future outcomes.
