Concept used:

Let

Consider null and Alternative hypothesis.

Null hypothesis,

Alternative hypothesis,

Here, the hypothesis test is left tailed.

Level of significance is 5%.

Determine the test statistics under Null hypothesis as follows.

Referring the table with 25 degree of freedom, to determine the P-value that is P - value > 0.10.

Using technology, P-value is 0.675 .

Since the P-value is 0.675 which is greater than level of significance

Therefore, the given data does not provide sufficient evidence to conclude that the intervention program reduces mean heart rate of urban drivers in Stockholm.

Read carefully and choose only one option

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.
