An independent-samples t test is performed on the samples below: Sample 1: M = 24.1, s2 = 32.02, n = 10 Sample 2: M = 19.4, s2 = 44.46, n = 10

1. Calculate the standard error for the t test (sM1-M2). (Round to 4 decimal places.)

2. Calculate the degrees of freedom for the t test.

3. Find the critical value of t with two tails and alpha = 0.05. (Keep 3 decimal places.)

4. Calculate the t test. (Round answer to two decimal places.)

5. The null hypothesis should be rejected for the t test.

6. Complete the APA formatted presentation of the t test. t( ______ ) = ________ , p ________ .05

Garage, Inc., has identified the following two projects:

A and B are mutually exclusive projects.

1. What is the crossover rate?

2. Which project should be accepted if the required rate of return is 13 percent?

3. Which project should be accepted if the required rate of return is 16 percent?

4. Which project should be accepted if the required rate of return is 19 percent?

5. A and B are independent projects. Assume that the required rate of return is 11 percent.

What is Project A's NPV?

An experiment was performed to determine the effect of four different chemicals on the strength of a fabric. These chemicals are used as part of the permanent press finishing process. Five fabric samples were selected, and a randomized complete block design was run by testing each chemical type once in random order on each fabric sample. The data are shown in Table below. test for differences in means using an ANOVA with α=0.01 Fabric Sample Chemical Type 1 2 3 4 5 1 1.3 1.6 0.5 1.2 1.1 2 2.2 2.4 0.4 2.0 1.8 3 1.8 1.7 0.6 1.5 1.3 4 3.9 4.4 2.0 4.1 3.4

Consider the following two mutually exclusive projects: Year Cash Flow (A) Cash Flow (B) 0 -$350,000 -$50,000 1 45,000 24,000 2 65,000 22,000 3 65,000 19,500 4 440,000 14,600 Whichever project you choose, if any, you require a 15 percent return on your investment. 1. If you apply the NPV criterion, which investment will you choose? Why? 2. If you apply the IRR criterion, which investment will you choose? Why? 3. If you apply the payback criterion, which investment will you choose? Why? 4. If you apply the discounted payback criterion, which investment will you choose? Why?

All other things being equal, the tax benefits of a tax credit outweigh the tax savings produced by a tax deduction because:

1) It reduces a taxpayer's tax liability

2) It reduces a taxpayer's taxable income

3) It reduces a taxpayer's capital gains

4) None of these

In 2019, what is the earned income credit allowed Don Andersen, a head of household taxpayer, assuming he has adjusted gross income of $9,500 (consisting of interest income of $3,500 and earned income of $6,000? He maintains his household with his daughter.

1) $2004

2) $2049

3) $2094

4) $0

5) None of the above answers are within $20 (plus or minus) of the correct answer.

Perform a Financial Analysis for a project XY.

Assume the projected costs and benefits for this project are spread over five years as follows:

•   Estimated costs are $225,000 in Year 1, $50,000 in Year 2 , 52,500 in Year 3, 55,000 in Year 4 and 57,500 in Year 5
•   Estimated benefits are $0 in Year 1 and $182,500 each year in Years 2, 3, 4 and 5
•   Use a 9 percent discount rate, and round the discount factors to two decimal places.

Create a spreadsheet to calculate and clearly display the following:

•   NPV
•   ROI
•   The year in which payback occurs.

In addition, write a paragraph explaining whether you would recommend investing in this project, based on your financial analysis

what does the polymerase chain reaction (PCR) accomplish?

1) PCR converts RNA to DNA

2) PCR corrects mutation in a gene

3) PCR makes many copies of DNA segment

4) PCR joins short segments of DNA to make one long segment

how does the ribosome select the next amino acid to add to a growing polypeptide chain?

1) the ribosome selects the amino acid that can form hydrogen bonds with the mRNA

2) the ribosome selects a tRNA that base-pairs with a codon

3) the ribosome senses that the amino acid fits into a binding pocket on the ribosome

4) the ribosome sense that the amino acid has the same codon as the DNA

At one college, the tuition for a full-time student is $8,000 per semester. It has been announced that the tuition will increase by 3 percent each year for the next 5 years. Write a program with a loop that displays the projected semester tuition amount for the next 5 years.

The program should print out the result in the form

In 1 year, the tuition will be $8002.3.
In 2 years, the tuition will be $8103.2.
In 3 years, …
In 4 years, …
In 5 years, …

(If, for example, the tuition would cost 8002.3 dollars in one year, etc.)

Sample Run

In 1 year, the tuition will be $8240.0.↵
In 2 years, the tuition will be $8487.2.↵
In 3 years, the tuition will be $8741.816.↵
In 4 years, the tuition will be $9004.07048.↵
In 5 years, the tuition will be $9274.192594400001.↵
