Find the mean of your data.
We can find the mean of the data by adding up all the pages in all the books and dividing by the total number of books.
Mean = (256 + 384 + 31 + 24 + 384 + 64 + 45 + 33 + 22 + 59 + 144 + 273 + 171 + 88 + 210) / 15
Mean = 1432 / 15
Mean = 95.47
Therefore, the mean number of pages in the selected books is approximately 95.47 pages.
To find the mean of the given data set, you need to add up all the values and then divide by the total number of values.
Let's calculate the mean step-by-step:
1. Add up all the values:
256 + 384 + 31 + 24 + 384 + 64 + 45 + 33 + 22 + 59 + 144 + 273 + 171 + 88 + 210 = 2528.
2. Determine the total number of values in the data set:
There are 15 values in the data set.
3. Divide the sum of the values by the total number of values:
2528 ÷ 15 ≈ 168.53.
Therefore, the mean of the given data set is approximately 168.53.
To find the mean of a data set, you need to compute the sum of all the values in the set and then divide it by the number of values.
In this case, we are given the number of pages in 15 different books.
To find the mean, follow these steps:
1. Add up all the given numbers:
256 + 384 + 31 + 24 + 384 + 64 + 45 + 33 + 22 + 59 + 144 + 273 + 171 + 88 + 210 = 2553
2. Divide the sum by the total number of values in the set (which is 15):
Mean = 2553 / 15 = 170.2
Therefore, the mean (average) number of pages in the selected books is 170.2 pages.
