A sample of 565 low-income and 680 high-income individuals was surveyed concerning their opinions on television violence. Among the low-income respondents, 400 believed that television violence is excessive, whereas 417 of the high-income respondents believed that television violence is excessive. Answer the following questions.
1. What is the null hypothesis? (1 point) 2. What is the research hypothesis? (1 point) 3. What is the proportion for each group? (2 point) 4. What is the z-statistic for the test? (2 points) 5. Using formal sentences, explain the results of the hypothesis test of the difference between the two proportions (alpha=.05). Use numbers to support your conclusion. (4 points)

Price Quantity
$1 8
2 7
3 6
4 5
5 4
6 3
a. Calculate the arc elasticities between each of the prices in the above demand curve (i.e. between $1 and $2, between $2 and $3, etc.)
b. Draw a graph showing the above demand curve and label the elasticities you just calculated between each price.
c. Calculate the total revenue (expenditures) at each price. Note the change in TR as price increases.
d. Generalize from the above -- what is the relationship between price elasticity and total revenue (expenditures).

Locking methods are one of the most common techniques used in concurrency control. There are different levels of lock use.
Make sure you clearly write down (a), (b) followed by your answers.
[6 marks] (a) Use the following scenario to illustrate and explain how a table-level lock and a page-level lock work.
Scenario:
Transaction 1 (T1) wants to update row 5 in Table A
Transaction 2 (T2) wants to update row 2 in Table A
Note: Page 1 contains rows 1-3 in Table A and Page 2 contains rows 4-6 in Table A
[4 marks] (b) Compare the advantages and disadvantages of a table-level lock and a page-level lock.
