I don't know where to begin with these problems would someone please call me
Find the median of each set of numbers
14. 1, 4, 9, 15, 25, 36
Find the mode of each set of numbers.
9, 8, 10, 9, 9, 10, 8
41, 43, 56, 67, 69, 72
Statistics. A salesperson drove 238, 159, 87, 163, and 198 miles (mi) on a 5-day trip. What was the mean number of miles driven per day?
Median is the middle number. First sort the numbers: I get 1,4,9,14,15,25,36. The middle (median) is 14.
Mode is the most common occurance.
You have two '8s', three '9s', two '10s' and one of everything else. The mode is therefore 9.
Mean is the average -- sum the series then divide by the number of numbers. mean=(238+159+87+163+198)/5
Sure, I can help you with these problems. Let's start with finding the median of the set of numbers: 1, 4, 9, 15, 25, 36.
To find the median, you need to arrange the numbers in ascending order. The set of numbers in ascending order will be: 1, 4, 9, 15, 25, 36.
The median is the middle value in this set. Since we have an even number of values, we take the average of the two middle values.
In this case, the two middle values are 9 and 15. So the median will be (9+15)/2 = 12.
Therefore, the median of the set 1, 4, 9, 15, 25, 36 is 12.
Now let's move on to finding the mode of the sets of numbers.
To find the mode, you need to determine the value(s) that appear most frequently in the set.
For the first set of numbers: 9, 8, 10, 9, 9, 10, 8.
The number 9 appears most frequently in this set, appearing three times. Therefore, the mode of this set is 9.
For the second set of numbers: 41, 43, 56, 67, 69, 72.
All the numbers in this set appear only once, so there is no mode.
Lastly, let's calculate the mean number of miles driven per day.
To find the mean, you need to sum up all the numbers and divide by the total number of values.
In this case, the total number of miles driven on the 5-day trip is 238 + 159 + 87 + 163 + 198 = 845.
To find the mean number of miles driven per day, divide this total by 5 (since there were 5 days).
Mean = 845 / 5 = 169.
Therefore, the mean number of miles driven per day is 169.
