Question

the table displays the mean name length for seven samples of students. sample mean name length 1 5.4 2 7.1 3 6.3 4 5.2 5 6.0 6 4.9 7 6.2 what can be said about the variation between the sample means? the variation between the sample means is small. the variation between the sample means is large. the variation shows that the values are far apart. the variation cannot be used to make predictions.

Explanation:

Step1: Identify the range of values

Find the maximum and minimum values. The maximum value among the sample - means is 7.1 and the minimum is 4.9.

Step2: Calculate the range

Range = Maximum - Minimum. So, Range = 7.1 - 4.9 = 2.2.

Step3: Analyze the range

A range of 2.2 for these sample - means is relatively small considering the values themselves are in the range of approximately 5 - 7.

Answer:

The variation between the sample means is small.
