Is the national crime rate really going down? Some sociologists say yes! They say that the reason for the decline in crime rates in the 1980s and 1990s is demographics. It seems that the population is aging, and older people commit fewer crimes. According to the FBI and the Justice Department, 70% of all arrests are of males aged 15 to 34 years†. Suppose you are a sociologist in Rock Springs, Wyoming, and a random sample of police files showed that of 37 arrests last month, 24 were of males aged 15 to 34 years. Use a 1% level of significance to test the claim that the population proportion of such arrests in Rock Springs is different from 70%.
What is the value of the sample test statistic? (Round your
answer to two decimal places.)
Find the Pvalue of the test statistic. (Round your answer
to four decimal places.)

Vandalay Industries is considering the purchase of a new machine for the production of latex. Machine A costs $2,310,000 and will last for 7 years. Variable costs are 36 percent of sales, and fixed costs are $138,000 per year. Machine B costs $4,800,000 and will last for 11 years. Variable costs for this machine are 28 percent of sales and fixed costs are $103,000 per year. The sales for each machine will be $9.6 million per year. The required return is 10 percent and the tax rate is 35 percent. Both machines will be depreciated on a straightline basis.

Geary Machine Shop is considering a fouryear project to improve its production efficiency. Buying a new machine press for $1,104,000 is estimated to result in $368,000 in annual pretax cost savings. The press falls in the MACRS fiveyear class (MACRS Table), and it will have a salvage value at the end of the project of $161,000. The press also requires an initial investment in spare parts inventory of $46,000, along with an additional $6,900 in inventory for each succeeding year of the project. 
Required : 
If the shop's tax rate is 32 percent and its discount rate is 16 percent, what is the NPV for this project? (Do not round your intermediate calculations.)

An amusement park studied methods for decreasing the waiting time (minutes) for rides by loading and unloading riders more efficiently. Two alternative loading/unloading methods have been proposed. To account for potential differences due to the type of ride and the possible interaction between the method of loading and unloading and the type of ride, a factorial experiment was designed. Use the following data to test for any significant effect due to the loading and unloading method, the type of ride, and interaction. Use . Factor A is method of loading and unloading; Factor B is the type of ride.

Please do not forget to write down all the names of your group members.
1. Please propose the mechanism for α−β CC bond cleavage of G6P. Draw the mechanism clearly, give the structures of the product, and then explain why steps 2 and 3 of glycolysis are necessary.
2. If glucose is labeled at C1 carbon (the C1 carbon is tagged with radioactive 14C), where would this labeled C atom be (which carbon atom number, draw the structure and label this carbon atom) when glucose has been metabolized to:
A. DHAP
B. GAP (you should be able to figure which carbon atom is the original C1 if you draw the mechanism of step 5)
C. After the reaction with G6PD enzyme (first step in pentose phosphate pathway)
D. After the oxidative decarboxylation step in PPP
E. How many % of the total pyruvate produced via glycolysis will carry this label?
3. A. What would be the fate of glucose in cells that need ATP, but not NADPH and R5P?
B. How about cells that need a lot of NADPH, but not R5P?
C. Finally, what would be the fate of glucose if the cells need a lot of R5P, but not NADPH?
Here are some hints to help you answer Q3.
1) Remember that the reactions in PPP (with the exception of the 3 in oxidative phase) are FULLY reversible.
2) Remember that glycolysis and PPP are linked by the common metabolites: F6P and GAP.
3) Although the stoichiometry of the reactions shown in class is different: glycolysis starts from 1 glucose molecule and PPP needs 3 G6P. In reality, our cells will always have more than 1 glucose molecule. 180 g of glucose (4.5 cans of soft drink) is 6.022 x 1023 molecules of glucose. Bottom line: to answer Q3, please do not worry about stoichiometry and whether there is enough glucose in the cells or not. There is truly plenty of glucose to go to any pathways as needed.
