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 value is the best estimate of the mean of the population? 11.0 12.3 17.3 20.9

Answer

Explanation:

Step1: Recall the concept of population - mean estimation

The best estimate of the population mean from sample means is the mean of the sample means. First, sum up all the sample means. Sum = (16.8 + 12.3+19.0 + 17.5+18.2+17.5) Sum = (101.3)

Step2: Calculate the number of samples

There are (n = 6) samples.

Step3: Calculate the mean of the sample means

Mean of sample means=(\frac{101.3}{6}\approx16.9). Among the given options, the value closest to the mean of the sample - means calculated is (17.3).

Answer:

17.3
