Please note that I can re-write your equation as follows:
x/6 + y/2 = 1
so we have:
x-intercept = 6
y-intercept = 2

We have to provide sufficient answers to support our knowledge. the book for the class is Behavioral Sciences STAT - With Access 2ND 15Author: Heiman, GaryISBN-13: 978-1-285-45814-4ISBN-10: 1-285-45814-1Edition/Copyright: 2ND 15Publisher: Wadsworth, Incwill copy and paste assignment below:Scenario: Imagine you are a researcher who is interested in studying whether sleep deprivation leads to increased reaction times (i.e., being slower) when driving. You randomly select a sample of 30 licensed drivers. Fifteen participants are randomly assigned to get 5 hours of sleep for three consecutive nights. The other 15 participants are randomly assigned to get 8 hours of sleep for three consecutive nights. For the purposes of this Assignment, assume that all participants sleep exactly the required amounts. After the third night, all participants take a driving simulation test that measures their reaction times.You can find the data for this Assignment in the Weekly Data Set forum. By Day 7To complete this Assignment, submit a response to each of the following. Use SPSS to determine if amount of sleep is related to reaction time.Explain whether the researcher should use an independent-samples t-test or a related-samples t-test for this scenario. Provide a rationale for your decision.Identify the independent variable and dependent variable.Knowing the researcher believes that people who sleep less will have slower reaction times, state the null hypothesis and alternate hypothesis in words (not formulas).Explain whether the researcher should use a one-tailed test or two-tailed test and why.Identify the obtained t value for this data set using SPSS and report it in your answer document.State the degrees of freedom and explain how you calculated it by hand.Identify the p value using SPSS and report it in your answer document.Explain whether the researcher should retain or reject the null hypothesis. Provide a rationale for your decision. Are the results statistically significant?Explain what the researcher can conclude about the relationship between amount of sleep and reaction times.Be sure to fully explain the rationale for your answer to each question, including evidence from the text and Learning Resources.Provide an APA reference list.Submit three documents for grading:Your text (Word) document with your answers and explanations to the assignment questions, your SPSS Data file, and your SPSS Output file.DATA SET BELOW:

Algebra Question
A delivery truck is transporting boxes of two sizes: large and small. The combined weight of a large box and a small box is 90 pounds. The truck is transporting 55 large boxes and 50 small boxes. If the truck is carrying a total of 4775 pounds in boxes, how much does each type of box weigh?

If a chief executive is randomly selected from this group what is the probability that the
executive is a Male?
What is the probability that a randomly selected executive from this group is a male
whose functional background is Finance?
Assume that an executive is selected and you are told that the executive’s functional
background was in operations. What is the probability that his executive is a male?
Assume that an executive is selected and you are told that the executive is female. What
is the probability the executive’s functional area is marketing?
Are gender and functional background independent for this set of executives?
Question 2
A manufacturing firm has two suppliers for an electrical component used in its process: one in
Mexico and one in China. The supplier in Mexico ships 82% of all the electrical components
used by the firm and has a defect rate of 6%. The Chinese supplier ships 18% of the electrical
components used by the firm and has a defect rate of 4%.
a. Draw a tree diagram for this question.
b. Calculate the probability that an electrical component is defective.
c. Suppose an electrical component is defective. What is the probability that component
was shipped from Mexico?

Question 4
A survey by KRC Research for US News reported that 30% of people plan to spend more on
eating out after they retire. If ten people are randomly selected, then determine the
Expected number of people who plan to spend more on eating out after they retire.
Standard deviation of the individuals who plan to spend more on eating out after they
retire.
c. Probability that two or fewer in the sample indicate that they actually plan to spend more
on eating out after retirement.
Question 5
A global financial institution transfers a large data file every evening from offices around the
world to its London headquarters. Once the file is received, it must be cleaned and partitioned
before being stored in the company’s data warehouse. Each file is the same size and the time
required to transfer, clean, and partition a file is normally distributed, with mean of 1.5 hours and
a standard deviation of 15 minutes.
a. If one file is selected at random, what is the probability that it will take longer than 1 hour
and 45 minutes to transfer, clean, and partition the file?
b. If a manager must be present until 90% of the files are transferred, cleaned, and
partitioned, how long will the manager need to be there?
c. What percentage of the data files will take between 70 minutes and 110 minutes to be
transferred, cleaned, and partitioned?
Question 6
When only the value-added time is considered, the time it takes to build a laser printer is thought
to be uniformly distributed between 8 and 15 hours.
What are the chances that it will take more than 10 value-added hours to build a printer?
How likely is it that a printer will require less than 9 value-added hours?
c. Suppose a single customer orders two printers. Determine the probability that the first
and second printer each will require less than 9 value-added hours to complete.
