Consider that Roane county, which calculated that the average firm size (in terms of number of
employees) is 150 with a median size of 50, while Anderson county calculated an average and
median size of 230 and 255 respectively. Officials from both counties are asking their state
legislatures for additional funds to accomodate their growing business size. Do you support
their requests, why or why not? Also, are there any additional statistics you might ask for
and why?

The Los Angeles City Controller's office calculated that in 2013, the city employed 47030 full-time employees and 10142 part-time employees. Assume that an outside advocacy group had been lobbying the Mayor's office to convert part-time workers into full-time workers throughout 2014. The Controller's office makes its calculations annually. Suppose that the outside advocacy group wanted to know the proportion of city employees (excluding per-event employees) who are full-time employees p in June 2014 to gauge if their lobbying efforts had been effective. Suppose that the group surveyed a random sample of 1000 city employees (excluding per-event employees) in June 2014 and found that 845 were full-time employees and 155 were part-time employees. If the advocacy group planned to use a one-sample z-test for a proportion to test their lobbying eforts, the appropriate null hypothesis would be and the appropriate alternative hypothesis would be

The highway department wants to estimate the proportion of vehicles on Interstate 25 between the hours of midnight and 5:00 A.M. that are 18-wheel tractor trailers. The estimate will be used to determine highway repair and construction considerations and in highway patrol planning. Suppose researchers for the highway department counted vehicles at different locations on the interstate for several nights during this time period. Of the 3,263 vehicles counted, 1,009 were 18-wheelers.a. Determine the point estimate for the proportion of vehicles traveling Interstate 25 during this time period that are 18-wheelers.b. Construct a 99% confidence interval for the proportion of vehicles on Interstate 25 during this time period that are 18-wheelers.

You may need to use the appropriate appendix table or technology to answer this question. Individuals filing federal income tax returns prior to March 31 received an average refund of $1,057. Consider the population of "last-minute" filers who mail their tax return during the last five days of the income tax period (typically April 10 to April 15). For a sample of 400 individuals who filed a tax return between April 10 and 15, the sample mean refund was $910. Based on prior experience, a population standard deviation of σ = $1,600 may be assumed. What is the test statistic? (Round your answer to two decimal places.) What is the p-value? (Round your answer to four decimal places.) p-value = Find the value of the test statistic. (Round your answer to two decimal places.) State the critical values for the rejection rule. (Use ? = 0.05. Round your answer to two decimal places. If the test is one-tailed, enter NONE for the unused tail.) test statistic≤test statistic≥
