Consider the probability

The probability that the z lies between 0 and 2.5 is equal to the area that lies under the curve from 0 and 2.5.

To find the probability look in the column headed by z for the value of 2.5 in appendix C.

In the column headed by A across 2.5 the corresponding value is 0.4938.

Thus the probability

So the value of

Hence the value of

A statistic is an unbiased estimator of a parameter when (a) the statistic is calculated from a random sample. (b) in a single sample, the value of the statistic is equal to the value of the parameter. (c) in many samples, the values of the statistic are very close to the value of the parameter. (d) in many samples, the values of the statistic are centered at the value of the parameter. (e) in many samples, the distribution of the statistic has a shape that is approximately NormalConstruct all random samples consisting three observations from the given data. Arrange the observations in ascending order without replacement and repetition.
