All applicants to the Police Academy are given an aptitude test, but the test has never been evaluated to see if test scores are in any way related to job performance. Use the percentages and the results of the Gamma test to interpret the association. Be sure that your answer answers all three questions about association and provide the PRE interpretation of the results. Finally, should the test continue to be administered? Why or why not?   Test Scores   Efficiency Low Moderate High Totals Low 12     6     7     25 Moderate 9       11   9     29 High 5       9     10   24 Totals 26 26 26 78

Please answer this, I need help.

The staff training center at a large regional hospital provides training sessions in CPR to all employees. Assume that the capacity of this training system was designed to be 1200 employees per year. Since the training center was first put in use, the program has become more complex, so that 1050 now represents the most employees that can be trained per year. In the past year, 950 employees were trained. The efficiency of this system is approximately approximately and its utilization is

A group collected data in an experiment to learn to draw suitable trendline in a graph. They don't know the theoretical model, so they are trying to determine one through this experiment. They used Excel to display the data and to find good fit. They tried linear, exponential, and power trendlines. The result of each trial is shown below. The title of the plot contains the name of the trendline used to fit. What should be their analysis based on the result they have so far? Exponential trendline 20 Power trendline 18 y = 0.8374e047x R? = 0.9851 16 y = 0.8045x1.538. R2 = 0.981 15 14 12 10 10 ..... 4 ..... ....... 2 1 3 4 1 7 Linear trendline 20 y = 3.0209x - 4.6606 15 R? = 0.9293 10 ........ 2 4 6 8 The linear trendline is good fit The exponential trendline is good fit Any one of the three trendlines seems good candidate The power trendline is the best fit 2. 2.

What is the percent yield for a reaction that has a theoretical yield of 24.02 g, if a student in a laboratory only obtains 18.72 g of product. Report the answer to four significant figures without the % sign.

If the cost to do business for a particular company is $4,000 for the startup fee plus $250 per day thereafter, write a graph linear equation that could represent the cost over time. How much cost will there be after 1 month (assume that there are 30 days in that month's time)?

The outside temperature can be estimated based on how fast crickets chirp. At 104 chirps per minute, the temperature is 6363 °F. At 176 chirps per minute, the temperature is 8181 °F. Using this information, you can make a formula that relates chirp rate to temperature. Assume the relationship is linear, that is the points form a straight line when plotted on a graph. What is the temperature if you hear 156156 chirps per minute?
