*Can you explain the results and consumption stream also?*

1.The difference between a Roth IRA and a traditional IRA is that in a Roth IRA taxes are paid on the income that is contributed but the withdrawals at retirement are tax-free. In a traditional IRA, however, the contributions reduce your taxable income, but the withdrawals at retirement are taxable. Assume you plan to devote $5,000 to retirement savings in each year. You will retire in 30 years and expect to live for an additional 20 years after retirement.

a. Assume the before-tax interest rate is 5%. What will be your after-tax 20-year retirement consumption stream if you choose to save in a traditional IRA? Assume your tax rate is fixed at 30%.

b. What will be your 20-year retirement consumption stream if you choose to save in a Roth IRA?

1) What are the advantages and disadvantages of microscale vs macroscale in the Organic laboratory?Think about some of the unique skills you have developed using microscale. Think about improved safety involved using microscale. Also think about things that were frustrating dealing with small quantities.

2) What are the advantages of writing your procedure immediately after performing an operation as opposed to writing it before doing the lab or even a day after doing the lab?

3) Why is it important to properly reference sources of information?

4) Define proper care and use of the following pieces of equipment or chemicals. autodelivery pipette, moisture sensitive chemicals ,salt plates toxic chemicals ,drying tubes ,melting point apparatus ,refractometer, thermometers, glassware ,syringes.

Section 179. (Obj. 2) Sand Corporation buys one asset in 2018---machinery costing $32,300,000. The machine was placed in service on June 2, 2018. Sand wants to elect the maximum Section 179 possible, even if some must be carried over to 2019. Sand's 2018 business income limitation (taxable income before Section 179 expense, but after all other expenses, including depreciation) is $167,000. A) Compute the maximum Section 179 Sand can elect to expense in 2018, the actual allowed 2018 expense deduction, and the Section 179 carryover to 2019. B) What is the regular depreciation deduction on the machine (7-year property; half-year convention) after taking into account the maximum section 179 deduction and assuming no bonus depreciation is clamied?

Anderson plans to acquire an automated assembly line with ten year life at a cost of sh 10 million, delivered and installed. He plans to use the equipment for only five years.He can borrow the required 10 million at a before cost of 10%.The estimated scrap value is sh 50,000 after ten years, but its estimated scrap value after five years is sh 1 million.He can lease the equipment for 5 years at a rental charge of sh 2.75m payable at the beginning of each year.The lessor will maintain the equipment. However if he buys he will bear the cost of maintenance of shs500,000 per year payable at the beginning of the year.The marginal tax rate is 40%

Analyze whether the company should purchase or lease the asset(

Banana Inc. is about to unveil their latest flagship phones, jPhone 11 pro in some few months. After a survey conducted by the company, they realized that the market demand for jPhone 11 pro is characterized by the following equation; P= 4000-0.5Qd. Also, the supply curve for Banana Inc is characterized by the following equation; P=0.5Qs.

a. With the information above, solve for the equilibrium price and quantity.

b. Suppose the government imposes a per unit tax of $100 per unit produced. Determine the new equilibrium price and quantity and illustrate your answer on the diagram. Also calculate the consumer surplus and producer surplus before and after the tax

c. Calculate the dead-weight loss as a result of the tax imposed by the government.

d. Calculate the government tax revenue.  (1 mark)

A student wants to prove that a GMAT prep company's claim that attending its 10-session prep course raises students' scores on the GMAT by an average of at least 50 points is false. In order to test the claim, they take eight students who have previously taken the GMAT and have them complete the 10 sessions. After completion, the students retake the GMAT and their scores are recorded. Test the theory at a 1% level of significance, using the paired difference test. You may assume that the differences in scores are normally distributed.

23A. A health psychologist is interested in whether certain situations produce different amounts of stress. A group of 15 students is randomly assigned to one of three groups. The students in group 1 have their stress levels measured immediately after returning from vacation. The students in group 2 have their stress levels measured after they have been in class for a week. The students in group 3 have their stress levels measured immediately before final exams week. Use this information to complete the ANOVA table provided below.

23B. Using the ANOVA table above, calculate the least biased measure of effect size.

23C. Interpret (in words) the magnitude of effect you computed above.

A 500 nF capacitor is initially connected to a 100 V DC voltage source. At some long time later, the switch is flipped and the capacitor is now connected to a 120 mH inductor.

a) What is the frequency of oscillation in the circuit after the switch is flipped.

b) After the switch is filpped, what would the peak current value be?

c) What is the maximum possible value for the energy stored in the inductor?

d) The energy in an LC circuit oscillates between the inductor and the capacitor. What is the charge on the capacitor when the energy in the inductor is half of its maximum value?

e) The energy in an LC circuit oscillates between the capacitor and the inductor. If I is initially zero when the switch is flipped (t = 0) how much time has elapsed before the energy in the inductor is half of its maximum.

1. A clinical trial was conducted to test the effectiveness of the drug zopiclone for treating insomnia in older subjects. Before treatment with zopiclone, 16 subjects had a mean wake time of 102.8 minutes. After treatment with zopiclone, the 16 subjects had a mean wake time of 98.9 minutes and a standard deviation of 42.3 minutes. Assume that the 16 sample values appear to be from a normally distributed population.

   1. a) Test the claim that after treatment with zopiclone, subjects have a mean wake time of less than 102.8 minutes at the ? = 0.05 level of significance. Use the critical value method. (Show all six steps for hypothesis testing.)

   2. b) Explain what it would mean to make a Type I error.

   3. c) Explain what it would mean to make a Type II error.

A researcher would like to evaluate the effectiveness of a pain-relief patch designed for lower back pain. Prior to testing the patch, each of n = 8 patients rates the current level of back pain on a scale from 1 to 10. After wearing the patch for 90 minutes, a second pain rating is recorded. The data are as follows:

                  Before      After

                        6            2

                        8            3

                        9            4

                        8            1

                      10           2

                        5            3

                        9            8

                        7            7
