Answer 1

The best estimate of the population means is always the sample mean. We have the sample values, using them we can find the sample mean.

The sum of the sampled rates = 248
Sample Size = 10

Mean value of the sample = Sum of Sample Rate/Sample Size

So,

Mean of the sample = 248/10 = 24.8

Therefore, we can say that the best estimate for the population mean is 24.8

Answer 2

Answer:

population mean for fuel consumption among vehicles is 24.8,

Step-by-step explanation:

Given : 32, 24, 14, 34, 26, 27, 31, 16, 18, 26.

To  find : What is the best estimate of the population mean for fuel consumption among vehicles

Solution : We have given that 32, 24, 14, 34, 26, 27, 31, 16, 18, 26.

Mean = $\frac{sum\ of\ data}{number\ of\ data}$.

Mean = $\frac{32+24+ 14+ 34+26+ 27+31+16+18+ 26}{10}$.

Mean= $\frac{248}{10}$.

Mean = 24.8

Therefore, population mean for fuel consumption among vehicles is 24.8
