Given that, the salesperson sample size
Typical mean sales
Standard deviation for a sample
(a) (In other words, the average sale per transaction is less than or equal to $4000. In other words, training designed to increase sales is ineffective.)
(b) (In other words, the average sale per transaction is higher than $4000. In other words, sales training is effective.)
(c) Test statistic: The test is one-tailed because the alternative hypothesis includes . (right-tailed).
P-value:
With the use of the formula "=T.DIST.RT(16.67,24)," the p-value obtained from the EXCEL is 0.
If , then reject the null hypothesis. If not, don't rule out the null hypothesis.
In this instance, p-value (0) is below the level of significance (0.05).
As a result, disprove the null hypothesis.
There is enough data to draw the conclusion that the average sale per transaction is higher than $4000. In other words, the sales training is effective.

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.
