Need this assignment completed by 10pm tonight. Had some lied about an emergency just because he decided that he didn't want to do i, so that's why I need it done today at this time. If you can do this assignment dont cha your mind and decide not to do it the last minute. This week you will begin working on Phase 4 of your course project. For Phase 4 of your course project, you will want to review your instructor's feedback from your Phase 1, Phase 2, and Phase 3 submissions to make any necessary corrections. Remember if you have questions about the feedback to ask your instructor for assistance. Corrections: Phase 1: incorrect:  median (incorrectly rounded), variance (divide by 59 instead of 60), standard deviation. Phase 2: Confidence intervals were incorrect, but only slightly - your s.d. was incorrect and should have been 8.92 - use this going forward. The CI = x-bar +/- t * s / sqrt (n), Phase 3: Use p for proportions or percents, this was a test of means, so use "mu" in hypotheses statements; μ = 65 for example; Your critical value was incorrect; use t-table instead of z; This whole exercise was just like example #4 in the Mod 3 course materials – Hypothesis Testing Explained and Explored;  Once you have made your corrections, you will compile your information from Phase 1, Phase 2, Phase 3 and your final conclusion into one submission and submit this as your rough draft for Phase 4 of the course project.

1. Need this assignment completed by 10pm tonight. Had some
lied about an emergency just because he decided that he didn't
want to do i, so that's why I need it done today at this time. If
you can do this assignment dont cha your mind and decide not
to do it the last minute.
This week you will begin working on Phase 4 of your course
project. For Phase 4 of your course project, you will want to
review your instructor's feedback from your Phase 1, Phase 2,
and Phase 3 submissions to make any necessary corrections.
Remember if you have questions about the feedback to ask your
instructor for assistance.
Corrections:
Phase 1: incorrect: median (incorrectly rounded), variance
(divide by 59 instead of 60), standard deviation.
Phase 2: Confidence intervals were incorrect, but only slightly -
your s.d. was incorrect and should have been 8.92 - use this
going forward.
The CI = x-bar +/- t * s / sqrt (n),
Phase 3:
Use p for proportions or percents, this was a test of means, so
use "mu" in hypotheses statements; μ = 65 for example;
Your critical value was incorrect; use t-table instead of z;
This whole exercise was just like example #4 in the Mod 3
course materials – Hypothesis Testing Explained and Explored;
Once you have made your corrections, you will compile your
information from Phase 1, Phase 2, Phase 3 and your final
conclusion into one submission and submit this as your rough
draft for Phase 4 of the course project. Below is a summary of
the expectations for Phase 4 of the course project:
Introduce your scenario and data set.

2. Provide a brief overview of the scenario you are given above
and the data set that you will be analyzing.
Classify the variables in your data set.
Which variables are quantitative/qualitative?
Which variables are discrete/continuous?
Describe the level of measurement for each variable included in
your data set.
Discuss the importance of the Measures of Center and the
Measures of Variation.
What are the measures of center and why are they important?
What are the measures of variation and why are they important?
Calculate the measures of center and measures of variation.
Interpret your results in context of the selected topic.

Median
Mode
Midrange
Range

Standard Deviantion
Discuss the importance of constructing confidence intervals for
the population mean.
What are confidence intervals?
What is a point estimate?
What is the best point estimate for the population mean?
Explain.
Why do we need confidence intervals?
Based on your selected topic, evaluate the following:
Find the best point estimate of the population mean.
Construct a
95%
confidence interval for the population mean. Assume that your
data is normally distributed and σ is unknown.
Please show your work for the construction of this confidence
interval and be sure to use the Equation Editor to format your
equations.

3. Write a statement that correctly interprets the confidence
interval in context of your selected topic.
Based on your selected topic, evaluate the following:
Find the best point estimate of the population mean.
Construct a
99%
confidence interval for the population mean. Assume that your
data is normally distributed and σ is unknown.
Please show your work for the construction of this confidence
interval and be sure to use the Equation Editor to format your
equations.
Write a statement that correctly interprets the confidence
interval in context of your selected topic.
Compare and contrast your findings for the 95% and 99%
confidence interval.
Did you notice any changes in your interval estimate? Explain.
What conclusion(s) can be drawn about your interval estimates
when the confidence level is increased? Explain.
Discuss the process for hypothesis testing.
Discuss the 8 steps of hypothesis testing?
When performing the 8 steps for hypothesis testing, which
method do you prefer; P-Value method or Critical Value
method? Why?
Perform the hypothesis test.
If you selected Option 1
:
Original Claim
: The average salary for all jobs in Minnesota is less than
$65,000.
Test the claim using α = 0.05 and assume your data is normally
distributed and σ is unknown.
If you selected Option 2:
Original Claim:
The average age of all patients admitted to the hospital with
infectious diseases is less than 65 years of age.
Test the claim using α = 0.05 and assume your data is normally

4. distributed and σ is unknown.
Based on your selected topic, answer the following:
Write the null and alternative hypothesis symbolically and
identify which hypothesis is the claim.
Is the test two-tailed, left-tailed, or right-tailed? Explain.
Which test statistic will you use for your hypothesis test; z-test
or t-test? Explain.
What is the value of the test-statistic? What is the P-value?
What is the critical value?
5.) What is your decision; reject the null or do not reject the
null?
Explain why you made your decision including the results for
your p-value and the critical value.
State the final conclusion in non-technical terms.
Conclusion
Recap your ideas by summarizing the information presented in
context of your chosen scenario.
Please be sure to show all of your work and use the Equation
Editor to format your equations.
This assignment should be formatted using APA guidelines and
a minimum of 2 pages in length.
