Answer:
(a) 48, 52, 54
(b) 6
(c) b, c
Step-by-step explanation:
The sample mean is the mean of the sample. The range of sample means is the difference between the largest and smallest. As with all sampling processes, more data gives a better estimate.
<h3>(a)</h3>The sample means are calculated in the attachment. For the different samples, they are ...
- 48
- 52
- 54
The range of the sample means is the difference between the largest and the smallest:
range = 54 -48 = 6
<h3>(c)</h3>More data is better, and the closer the estimates are to each other, the better confidence they offer. The true statements are ...
- A single sample mean will tend to be a worse estimate than the mean of the sample means.
- The closer the range of sample means is to zero, the more confident they can be in their estimate.
