Question

A 2-column table with 8 rows. Column 1 is labeled Student with entries 1, 2, 3, 4, 5, 6, 7, 8. Column 2 is labeled Mean Word Length with entries 7. 1, 4. 5, 6. 9, 5. 2, 5. 0, 4. 7, 6. 1, 4. 5.

Given this data, what is the range of the average word lengths?




Is the variation between sample means large or small?

Answer 1

The range of the average word lengths is 7.0 - 2.0 = 5.0.

The variation between sample means is small because the differences between the sample means are not very large.

Answer 2

i have the answer but aint giving it for ONLY 5 points

Step-by-step explanation:

ok fine ill give it here

The range of the average word lengths can be found by subtracting the minimum value from the maximum value. In this case, the minimum value is 4 and the maximum value is 6.9. Therefore, the range of the average word lengths is 6.9 - 4 = 2.9.

To determine whether the variation between sample means is large or small, we can calculate the standard deviation of the sample means. However, we need to know the sample size to do this. Since the sample size is not provided, we cannot determine the variation between sample means.
