In 2021, the Westgate Construction Company entered into a contract to construct a road for Santa Clara County for $10,000,000. The road was completed in 2023. Information related to the contract is as follows:

Westgate recognizes revenue over time according to percentage of completion.

5. Calculate the amount of revenue and gross profit (loss) to be recognized in each of the three years assuming the following costs incurred and costs to complete information. (Do not round intermediate calculations and round your final answers to the nearest whole dollar amount. Loss amounts should be indicated with a minus sign.)

1. An error in the physical count of goods on hand at the end of the current period resulted in a $2,500 overstatement of the ending inventory. The effect of this error in the current period is to:

a) overstate cost of goods sold

b) understate cost of goods available for sale.

c) understate gross profit.

d) overstate net income.

e) understate ending retained earnings.

2. Under the equity method of accounting for investments in common stock, when a dividend is received from the investee company:

a) the Dividend Revenue account is credited.

b) the Investments account is increased.

c) no entry is necessary.

d) the Dividend Revenue account is debited.

e) the Investments account is decreased.

3. A purchase of common stock of Ajax Corporation for $14,000 was sold three months later for $15,000. The entry to record the sale would include a:

a) debit to Cash of $14,000.

b) credit to Gain on Sale of Investments of $1,000.

c) credit to Investments of $15,000.

d) credit to Interest Revenue of $1,000.

e) debit to Gain on Sale of Investments of $1,000.

The following are three independent, unrelated sets of facts relating to accounting changes.

For each of the situations described, provide the information indicated below.

Type of accounting change.

Manner of reporting the change under current generally accepted accounting principles, including a discussion where applicable of how amounts are computed.

Effect of the change on the balance sheet and income statement.

Postpartum Depression

In this assignment we will look at women with birth depression and how estrogen treatment can affect depression. The data is contained in the data depression footprint.

Prior to treatment, all women were assessed after the Edinburgh Postnatal Depression Scale (EPDS). High EPDS scores indicate severe depression. Patients were randomly assigned to either receive placebo (group = 0, n = 18) or estrogen (group = 1, n = 22) as treatment. The EPDS score was again measured after 3 months of treatment.

In this task you should choose whether to perform a regular two-sample T-test / paired t-test, or if you should also perform a non-parametric test (Wilcoxon-Mann-Whitney test / Wilcoxon pairing test) when we To check if treatment has an effect. To determine this, check the assumptions that are the basis for performing a t-test. For a two-sample t-test, make sure that the two samples are normally distributed and for a paired t-test, be sure to check that the difference between the paired data is normally distributed. Do not use log-transformation in this task, even if it is possible.

1- Give a descriptive description of the variables EPDS prior to treatment initiated for each of the treatment groups (placebo and estrogen). Write a brief summary of what you find. Is there a significant difference between the two treatment groups in EPDS score before receiving treatment?

2- Is there a significant difference between the two treatment groups in 3 months of treatment?

3- Just look at those who have received estrogen as treatment. Have they had a significant change in EPDS score from before treatment to after 3 months of treatment?
4- Now look at those who have received a placebo. Have they had a significant change in EPDS score from before treatment to after 3 months of treatment?
5- Check the change from before treatment to after 3 months of treatment for the placebo and estrogen groups. Perform a test and check whether estrogen has had an effect on the EPDS score.

Which of the following portfolio(s) is(are) on the efficient frontier?
A. The portfolio with 20 percent in A and 80 percent in B.
B. The portfolio with 15 percent in A and 85 percent in B.
C. The portfolio with 26 percent in A and 74 percent in B.
D. The portfolio with 10 percent in A and 90 percent in B.
E. A and B are both on the efficient frontier.

Here is the answer, but I don't understand how they got it:

The Portfolio's E(Rp), sp, Reward/volatility ratios are 20A/80B: 8.8%, 1.05%, 8.38; 15A/85B: 8.53%, 1.06%, 8.07; 26A/74B: 9.13%, 1.05%, 8.70; 10A/90B: 8.25%, 1.07%, 7.73. The portfolio with 26% in A and 74% in B dominates all of the other portfolios by the mean-variance criterion.

Refer to the accompanying data set and construct a 90​% confidence interval estimate of the mean pulse rate of adult​ females; then do the same for adult males. Compare the results.

A college physics professor thinks that two of her sections scored differently on the final exam.  

She collects the scores for the two classes and stores them in a file.

We do not know anything about the test score distributions.

Answer the following. Use alpha = 0.05.

a). What is the value of the test statistic?

b). What is the p-value?

c). Is she correct in stating that the final exam scores from the two sections are not equal to each other?

Here are the score sets

Set 1: 74, 79, 65, 58, 67, 61, 63, 64, 62, 72, 66, 58, 66, 63, 61, 73, 77, 68, 62, 67, 81, 80, 58

Set 2: 75, 77, 76, 82, 88, 91, 92, 70, 89, 85, 71, 82, 91, 77, 67, 87, 92, 88, 94, 85, 97, 93, 74

Record companies prioritise their new releases of music each by the senior management deciding on which new releases should receive priority in marketing to radio stations and music stores. Here the musician might be considered a ‘principal’ who uses the services of the record company, the ‘agent’, to produce and market their sound recording. Does the description of the prioritising of new releases suggest that an incentive problem may arise between the principal and agent? Evaluate and comment upon the following types of contracts from the musician’s perspective. The record company receives a fixed amount of total revenue. The record company receives a fixed amount of total revenue plus payment for the costs of advertising. The record company receives a proportion of the total profits.
