Does it take more time for seeds to germinate if they are near rock music that is continuously playing compared to being near classical music? The 53 seeds that were exposed to rock music took an average of 20 days to germinate. The standard deviation was 13 days. The 45 seeds that were exposed to classical music took an average of 15 days to germinate. The standard deviation for these seeds was 7 days. What can be concluded at the α = 0.01 level of significance?

For this study, we should use

The null and alternative hypotheses would be: H 0 : (please enter a decimal) H 1 : (Please enter a decimal)

The test statistic = (please show your answer to 3 decimal places.)

The p-value = (Please show your answer to 4 decimal places.)

The p-value is α

Based on this, we should the null hypothesis.

Thus, the final conclusion is that ...

The results are statistically significant at α = 0.01, so there is sufficient evidence to conclude that the mean germination time for the 53 seeds exposed to rock music that were observed is more than the mean germination time for the 45 seeds that were exposed to classical music that were observed.

The results are statistically insignificant at α = 0.01, so there is statistically significant evidence to conclude that the population mean time for seeds exposed to rock music to germinate is equal to the population mean time for seeds exposed to classical music to germinate.

The results are statistically significant at α = 0.01, so there is sufficient evidence to conclude that the population mean time for seeds exposed to rock music to germinate is more than the population mean time for seeds exposed to classical music to germinate.

Harper Theater is located in Midtown Mall. The cashier’s booth is near the entrance to the theater. Two cashiers are employed. Once works from 1-5 p.m., the other from 5-9 P.M.   Each cashier is bonded. The cashiers receive cash from customers and operate a machine that ejects serially numbered tickets. The rolls of tickets are inserted and locked into the machine by the theater manager at the beginning of each cashier’s shift.

After purchasing a ticket, the customer takes the ticket to an usher stationed at the entrance to the theater lobby some 60 feet from the cashier’s booth. The usher tears the ticket in half, admits the customer, and returns the ticket stub to the customer. The other half of the ticket is dropped into a locked box by the usher.

At the end of each cashier’s shift, the theater manager removes the ticket roll from the machine and makes a cash count. The cash count sheet is initialed by the cashier. At the end of the day, the manager deposits the receipts in total in a bank night deposit vault located in the mall. The manager also sends copies of the deposit slip and the initialed cash count sheets to the theater company treasurer for verification and to the company’s accounting department. Receipts from the first shift are stored in a safe located in the manager’s office.

1.) Identify the internal control procedures and their application to the cash receipts transactions of the Harper Theater. You will find the Internal Control Procedures on pages 433 through 435 of your textbook. For each Internal Control Procedure described in your textbook, identify any Internal Control Procedures that Harper Theater has in place and/or is missing. Be specific and use at least 300 words for your answer.
Be specific and use at least 300 words for your answer.

2.) If the usher and cash decide to collaborate to misappropriate cash, what actions might they take? For each action, what internal control might be employed to stop the misappropriation of cash? Be specific and use at least 200 words for your answer.

3.) Use complete sentences and good grammar.  

Near the endpoint, the red color of the silver chromate forms, but then disappears, as you swirl. This is because the Ksp of silver chromate may be temporarily exceeded locally (where the silver nitrate is added), but as you swirl, the chloride ions still in solution convert the silver chromate into silver chloride. Write an equation for this process, (the process of converting the silver chromate into white silver chloride) and calculate the equilibrium constant of the reaction in terms of the solubility products of silver chloride and silver chromate.

Ksp = 1.6 x 10-10 for AgCl Ksp = 1.1 x 10-12 for Ag2CrO4

b.   Assume the chromate concentration of indicator in the flask is 0.0050 M. What is the concentration of Cl- remaining in the flask when silver chromate first precipitates (that is, at the endpoint of the titration).

c.   What percentage of the Cl- in the original unknown remains when the endpoint is reached? You should use your answer to question 2, and estimate the volume of solution in the flask.

Assuming the elastic solution for the stresses near a crack tip is valid in the case of small-scale yielding, determine r_p(q) for Mode I and Mode II  in plane stress and plane strain. Plot a nondimensional r_p(q), ( r_p/ r_p(Irwin)) in the vicinity of the crack tip for several different values of Poisson's ratio.

Determine the following parameters if the overall efficiency of the module is given as 15%:

a) The peak power of the solar generator at each site.
b) The total solar generator area for each site.
c) The amount of land area required at each site.
d) Discuss any technical, environmental, operational and financial implications of using solar power modules at the two sites.
