Question

A professional employee in a large corporation receives an
average of u=40 e-mails per day. Most of these e-mails are from
other employees in the company. Because of the large number of
e-mails, employees find themselves distracted and are unable to
concentrate when they return to their tasks. In an effort to reduce
distraction caused by such interruptions, one company established a
priority list that all employees were to use before sending an
e-mail. One month after the new priority list was put into place, a
random sample of 33 employees showed that they were receiving an
average of Xbar=33.4 e-mails per day. The computer server through
which the e-mails are routed showed that o=17.5. Use a 5% level of
significance to test the claim that there has been a change (either
way) in the average number of e-mails received per day per
employee. Are the data statistically significant at level
*α*? Based on your answers, will you reject or fail to
reject the null hypothesis?

Group of answer choices

The *P*-value is greater than the level of significance
and so the data are not statistically significant. Thus, we reject
the null hypothesis.

The *P*-value is greater than the level of significance
and so the data are statistically significant. Thus, we fail to
reject the null hypothesis.

The *P*-value is less than the level of significance and
so the data are statistically significant. Thus, we reject the null
hypothesis.

The *P*-value is greater than the level of significance
and so the data are not statistically significant. Thus, we fail to
reject the null hypothesis.

The *P*-value is greater than the level of significance

Based on information from the Federal Highway Administration web
site, the average annual miles driven per vehicle in the United
States is 13.5 thousand miles. Assume σ ≈ 650 miles. Suppose that a
random sample of 36 vehicles owned by residents of Chicago showed
that the average mileage driven last year was 13.2 thousand miles.
Would this indicate that the average miles driven per vehicle in
Chicago is different from (higher or lower than) the national
average? Use a 0.05...
