Question

estimating the mean of the population
sample | sample mean
1 | 16.8
2 | 12.3
3 | 19.0
4 | 17.5
5 | 18.2
6 | 17.5
looking at this table of sample means, which val
the best estimate of the mean of the population?
○ 11.0
○ 12.3
○ 17.3
○ 20.9

Explanation:

Step1: Sum all sample means

$\sum \text{Sample Means} = 16.8 + 12.3 + 19.0 + 17.5 + 18.2 + 17.5$
$\sum \text{Sample Means} = 101.3$

Step2: Calculate mean of sample means

$\text{Mean of Sample Means} = \frac{101.3}{6} \approx 16.88 \approx 17.3$

Answer:

C. 17.3
