1: Why in your opinion did Jim’s accountant recommend the average cost method and what difference is there with the three other methods? Explain the main characteristics of each method of valuation of the inventory and the consequences they may have on the valuation of the inventory and determination of the net income in case of price fluctuation.

ABC Ltd has accounts receivable of $70 600 at 30 April, 2019. An analysis of the accounts shows these amounts as follows:

Credit terms are 2/7, n/30. At 30 April, 2019, there is a $2000 credit balance in Allowance for Doubtful Debts before adjustment. The entity uses the ageing of accounts receivable basis for estimating uncollectable accounts. Estimates of bad debts are as follows:

Required:

a)     Determine the total estimated uncollectable. (1 mark)

b)     Prepare the adjusting entry at 30 April, 2019 to record bad debts expense. (1 mark)

c)     In May, 2019, a $2 500 customer balance is determined to be uncollectable. Prepare the journal entry. (1 mark)

d)     Repeat c) assuming that the direct write-off method is used in this business. (1 mark)

(Both account names and figures should be correct in order to award marks.

2. Let’s use the data from the sea ice extent by year. a. Do a t-test to determine if the slope = 0, give null and alternative hypotheses, test statistic, pvalue, decision and interpretation. b. Construct a residual plot vs fitted values. c. Look at a histogram of the residuals. d. Are there any obvious outliers? Find that observation that is the most glaring and find out how many standard deviations it is from the mean. Can this be justified to be removed? e. Are the assumptions for regression met? (Linearity, Constant Standard Deviation and Normality of errors). If not, which one is violated.

Need this in C# and also the Pseudocode.

Program 4: In 1789, Benjamin Franklin is known to have written “Our new Constitution is now established, and has an appearance that promises permanency; but in this world nothing can be said to be certain, except death and taxes.” Our federal tax system is a “graduated” tax system which is broken into seven segments. Essentially, the more you make, the higher your tax rate. For 2018, you can find the tax brackets here. Your task is to design (pseudocode) and implement (source code) a program that asks the user for a salary and calculates the federal tax owed. Note, that only the money above a particular tax bracket gets taxed at the higher rate. For example, if someone makes $10,000 a year, the first $9525 gets taxed at 10%. The “excess” above that ($475) gets taxed at 12%. Note: work through at least three (3) examples of this by hand before designing the code. It will save you significant time.  

Sample run 1:

Enter your salary to the nearest dollar: 2000

Total tax owed is: $200

Sample run 2:

Enter your salary to the nearest dollar: 40000

Total tax owed is: $4739

Sample run 3:

Enter your salary to the nearest dollar: 100000

Total tax owed is: $18289

A medical researcher wants to compare the pulse rates of smokers and non-smokers. He believes that the pulse rate for smokers and non-smokers is different and wants to test this claim at the 0.02 level of significance. A sample of 56 smokers has a mean pulse rate of 88, and a sample of 39 non-smokers has a mean pulse rate of 86. The population standard deviation of the pulse rates is known to be 8 for smokers and 8 for non-smokers. Let μ1 be the true mean pulse rate for smokers and μ2 be the true mean pulse rate for non-smokers.

Step 1 of 5 : State the null and alternative hypotheses for the test.

The conformity of serial production parts is verified using a non-destructive test.
However, the test is not 100% reliable. Indeed, previous statistics show that 12% of compliant parts are classified as non-compliant, and 10% of non-compliant parts are classified as compliant.
We also know that 20% of the production parts are really non-compliant.
This test is used to verify the compliance of a sample of 41 randomly selected parts in this production
a) Calculate the probability that 7 pieces of the sample are classified as non-compliant by the test.
b) Given that 7 parts in the sample are classified as nonconforming by the test, what is the probability that in fact there are exactly 11 nonconforming parts?

Overview

In this lab, you will design an Enhanced Entity Relationship (EER) diagram to improve on the database design that you have worked on in the previous weeks.

The new design will include additional improvements such as:

1. Inheritance Relationships
2. Constraints
3. Union Types

A clear and well-documented explanation of all your modifications and the EER diagram.

can you please give me an example of how to start this or what am i supposed to do!!!
