22. Local residents have requested a traffic light at the intersection of Polk Road and Vine Street. They claim that the intersection has become unsafe for their children due to the high volume of drivers using these roads as shortcuts during rush hour from 4 p.m. to 6 p.m. In response, the street department installed a device that would count cars going through the intersection. The device counted the total number of cars each day for a two-week period. The department used the results to determine the average number of cars passing through the intersection each day. They decided the number was normal for an intersection with no light, and refused the residents’ request. Explain how the residents can claim that the method the department used to collect the data does not provide valid information for evaluating their request. Explain how the department’s method can be altered to provide more valid data. (2 points)

Question 34 – Scoring GuidelinesPoints Student Response

4 The focus of this item is the comparison of a flat raise for all employees to a raise based upon a percentage of their current salaries. The response indicates that the advantage of one plan versus the other plan depends on the employee’s annual salaries. The response determines that more employees would likely vote for the flat $500 raise than the 2% raise since more employees would benefit more from theflat $500 raise.

3 The response clearly addresses the key aspects of the task; however, it includes errors in completing one or two components. 3 point sample answer: For example, the response may:Demonstrate a correct mathematical procedure but contain a computational error (e.g. in finding the effect of a 2% raise or totaling the number of employees who would vote for each option). The statement about the result of the vote is consistent with work shown.
