You are hired as a junior manager at a state-owned institution at the beginning of 2021 with a salary of $100,000. You must choose between two retirement plans in the first week of your employment. This choice cannot be reversed. The two alternatives are:

• the state’s defined benefit plan (DBP): under which you will receive annual retirement benefits determined by the following formula: 1.5% * years of service * salary at retirement.
• a defined contribution plan (DCP): under which the institution will contribute each year an amount equal to 8% of your salary to your retirement fund.

You assume that salaries will rise by 3% a year, the interest rate and return of retirement assets will roughly match the market index return of 8%, you will retire after 35 years (end of 2055), and receive retirement payment for the subsequent 25 years (between the end of 2055 and the end of 2080).

1.) What is the amount of PBO under the DBP for your employer at the end of 2021? Hint: present value at the end of 2021

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.

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?

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?

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

The Nero Match Company sells matchboxes that are said to contain an average of 40 matches per box with a standard deviation of 9 matches. A random sample of 94 Nero matchboxes shows the average number per box to be 41.8 Using a​ 1% level of​ significance, can you say that the average number of matches per box is more than​ 40?

1) What type of hypothesis test is​ this?

​2) State the hypotheses.  

​3) Calculate the value of the Test Statistic.

​4) Calculate the​ P-Value.

​5) What is the​ decision?
