An amusement park, whose customer set is made up of two markets, adults and children, has developed demand schedules as follows: Price ($) Quantity Adults Children 5 15 20 6 14 18 7 13 16 8 12 14 9 11 12 10 10 10 11 9 8 12 8 6 13 7 4 14 6 2 The marginal operating cost of each unit of quantity is $5. Because marginal cost is a constant, so is average variable cost. Ignore fixed costs. The owners of the amusement part want to maximize profits. Calculate the price, quantity, and profit if: The amusement park charges a different price in each market. The amusement park charges the same price in the two markets combined. Explain the difference in the profit realized under the two situations.

A study examines whether an enriched vs. normal rearing environment changes social behavior in rats. Two rats from each of eight litters are randomly assigned to an enriched vs standard environment. The scores of their social behavior are assessed by a standard rating scale, and are as follows:

a) Conduct a matched-pair t test to test the null hypothesis that the mean difference in sociability equals 0.

b)The researcher conducted a matched-pair t test because she anticipated that the scores of rats reared in the same litter are not independent of one another. Test this hypothesis by computing the Pearson correlation between the enriched and standard scores and whether it is significantly different from 0.

1. Have you ever purchased an article of clothing (dress, sports jacket, etc.), worn the item once to a party, and then returned the purchase? This is called a one-time fling. About 10% of all adults deliberately do a one-time fling and fell no guilt about it. In a group of seven adult friends, what is the probability that:
   1. No one has done a one-time flng?
   2. At least one person has done a one-time flng?
   3. No more than two people have done a one-time fling?
   4. What is the average number (expected value) of people who have done a one-time fling?
   5. What is the standard deviation

Perpetual Inventory Using FIFO

The following units of a particular item were available for sale during the calendar year:

The firm maintains a perpetual inventory system. Determine the cost of goods sold for each sale and the inventory balance after each sale, assuming the first-in, first-out method. Present the data in the form illustrated in Exhibit 3. Under FIFO, if units are in inventory at two different costs, enter the units with the LOWER unit cost first in the Cost of Goods Sold Unit Cost column and in the Inventory Unit Cost column.

Use the following information about a hypothetical government security dealer named J.P. Groman. (Market yields are in parentheses; amounts are in millions.)

a. What is the repricing or funding gap if the planning period is 30 days? 91 days? 2 years? (Recall that cash is a non-interest-earning asset.)
b. What is the impact over the next 30 days on net interest income if all interest rates rise by 50 basis points?
c. The following one-year runoffs are expected: $11 million for two-year T-notes, $21 million for the eight-year T-notes. What is the one-year repricing gap?
d. If runoffs are considered, what is the effect on net interest income at year-end if interest rates rise by 50 basis points?

A study of the effect of television commercials on 12-year-old children measured their attention span, in seconds. The commercials were for clothes, food, and toys.

1. Complete the ANOVA table. Use 0.05 significance level. (Round the SS and MS values to 1 decimal place and Fvalue to 2 decimal places.)

2. Find the values of mean and standard deviation. (Round the mean and standard deviation values to 3 decimal places.)

3. Is there a difference in the mean attention span of the children for the various commercials?

4. Are there significant differences between pairs of means?

Cain Components manufactures and distributes various plumbing products used in homes and other buildings. Over time, the production staff has noticed that products they considered easy to make were difficult to sell at margins considered reasonable, while products that seemed to take a lot of staff time were selling well despite recent price increases. A summer intern has suggested that the cost system might be providing misleading information.

The controller decided that a good summer project for the intern would be to develop, in one self-contained area of the plant, an alternative cost system with which to compare the current system. The intern identified the following cost pools and, after discussion with some plant personnel, appropriate cost drivers for each pool. There were:

In this particular area, Cain produces two of its many products: Standard and Deluxe. The following are data for production for the latest full year of operations.

Problem 9-62 (Algo) Activity-Based Costing and Predetermined Overhead Rates (LO 9-3, 5, 6)

Required:

a. The current cost accounting system charges overhead to products based on machine-hours. What unit product costs will be reported for the two products if the current cost system continues to be used?

b. The intern suggests an ABC system using the cost drivers identified above. What unit product costs will be reported for the two products if the ABC system is used?

any help with this problem would be awesome

An insurance company has compiled the accompanying data relating the age of drivers and the accident rate (the probability of being involved in an accident during a 1-year period) for drivers within that group. Age Group Insured Drivers (%) Accident Rate (%) Under 25 16 5.5 25–44 40 3.5 45–64 30 2 65 and over 14 5 What is the probability of the following? (Round all answers to two decimal places.) (a) An insured driver selected at random will be involved in an accident during a particular 1-year period. (b) An insured driver selected at random who is involved in an accident is under 25.

The Garrison Company manufactures two products: Oxy Cleaner and Sonic Cleaner. The costs and revenues are as follows:

Total demand for Oxy is 10,000 units and for Sonic is 6,000 units. Machine time is a scarce resource. During the year, 50,000 machine hours are available. Oxy requires 4 machine hours per unit, while Sonic requires 2.5 machine hours per unit.

What is the maximum contribution margin Garrison can achieve during a year?

$444,250.

$1,014,000.

$488,000.

$855,500.
