Following the guidance of Strunk and White, write a short sentence below that correctly ends with an exclamation point.

When we talked about writing for resumes as well as interviewing for positions, we discussed the PSR method of describing a situation that demonstrated your skills.  This was useful for both detailing your work history in your resume, or in responding to an interview question.  What does the acronym PSR refer to?

Using question 29, state the conclusion (in clear English).

One of Strunk and White’s rules is to “Write with nouns and verbs.”   What does that mean?

Since the Fair Labor Standards Act was passed in 1938, the standard work week in the United States has been 40 hours. Suppose that this data set on StatCrunch shows the number of hours worked in a week for a random sample of 50 U.S. workers. Do the data provide evidence that the true mean number of hours worked is different than 40 hours? State the null and alternative hypotheses for this situation. 

Select which of the following statement(s) is/are true about hypothesis test. Note: there may be more than one true statement.

Using question 5, compute the 95% confidence interval for the unknown population parameter, the true mean number of hours worked by U.S. workers. Write the lower and upper bounds of your confidence interval to one decimal place.

Using question 5, state the summary statistics (data from the sample – sample mean, sample standard deviation, sample size, and degrees of freedom).

True or False? Clearly explain your answer.  If we do not reject a null hypothesis at α = 0.01, we also do not reject the null hypothesis at α = 0.05?
