Explanation & Answer
So this sort of demonstrates the importance of parenthesis when dealing with exponential equations. For the first quantity there are it is - 6^2 which is -36 and the second quantity is (-1)^4 which equals 1. They add up to -35. Let me know if you have any specific questions.

University of Phoenix Use of Public Key Cryptosystem Paper Project
RSA is the most widely used public key cryptosystem. In this discussion, you will apply RSA to post and read messages. For this reflection discussion, use the prime numbers p = 3 and q = 11.Using the public key e = 3, post a phrase about something that you found interesting or relevant in this course. Include only letters and spaces in your phrase. Represent the letters A through Z by using the numbers 01 through 26, and represent a space by the number 32. Treat upper case and lower case letters as the same.Optional: If you want to include punctuation characters, you can use the numbers 27 through 31 for that, but you must inform your classmates that you did.How did you calculate your value for d? As a check, the phrase “A CAB” would be represented by “01 32 03 01 02” and would be encrypted as “01 32 27 01 08”.

Steps to Complete the Week 7 Lab
Step 1: Find these articles in the Chamberlain Library. Once you click each link, you will be logged into the Library and then click on "PDF Full Text".
First Article: Confidence Intervals, Part 1 (Links to an external site.) (Links to an external site.)Links to an external site. (Links to an external site.)
Second Article: Confidence Intervals, Part 2 (Links to an external site.) (Links to an external site.)Links to an external site. (Links to an external site.)
Step 2: Consider the use of confidence intervals in health sciences with these articles as inspiration and insights.
Step 3: Using the data you collected for the Week 5 Lab (heights of 10 different people that you work with), discuss your method of collection for the values that you are using in your study. What are some faults with this type of data collection? What other type of data collection could you have used, and how might this have affected your study?
Step 4: Now use the Week 6 Spreadsheet (Links to an external site.) to help you with calculations for the following questions/statements.
Give a point estimate for the average height of all people at the place where you work. Start by putting the ten heights you are working with into the blue Data column of the spreadsheet. What is your point estimate, and what does this mean?
Find a 95% confidence interval for the true mean height of all the people at your place of work. What is the interval?
Give a practical interpretation of the interval you found in part b, and explain carefully what the output means. (For example, you might say, "I am 95% confident that the true mean height of all of the people in my company is between 64 inches and 68 inches").
Post a screenshot of your work from the t value Confidence Interval for µ from the Confidence Interval tab on the Week 6 Excel spreadsheet
Step 5: Now, find a 99% confidence interval for the same data. Would the margin of error be larger or smaller for the 99% CI? Explain your reasoning.
Step 6: Save the Week 7 Lab document with your answers and include your name in the title.
Step 7: Submit the document.
Grading
This activity will be graded based on the Week 7 Lab Rubric.

Business Statistics Discussion
Topic: Analyzing Your Weather!
“Climate is what you expect; Weather is what you get,” is often attributed to Mark Twain, Robert Heinlein, and several others. Here is your chance to analyze the weather patterns in your area with the numerical measurements from this unit.
Main Post: Export the Weather Summary for your city for the recent month.
1) Export your daily weather summary for ZIP code 31905 from NOAA’s Climate Data Online Search. Detailed instructions and video found in the Unit 2 LiveBinder.
2) Open the data in Excel and select one of the quantitative weather variables to analyze.
3) Run Data Analysis->Descriptive Statistics on this variable. Copy and paste the Summary Table directly into your post or share it as an attachment.
4) Calculate the 1st and 3rd quartile of your variable.
5) Clearly state your 5-Number Summary (Min, Q1, Median, Q3, Max) in your post
See Example and DB starter video in the Unit 2 LiveBinder.

Learn By doing
In this activity you will learn to use StatCrunch to perform a two-sample t-test.Some features of this activity may not work well on a cell phone or tablet. We highly recommend that you complete this activity on a computer.Here are the directions and grading rubric for the Learn by Doing discussion board exercises. A list of StatCrunch directions is provided at the bottom of this page.ContextDo undergraduates sleep less than graduate students?A student conducted a study of sleep habits at a large state university. His hypothesis is that undergraduates will party more and sleep less than graduate students. He surveyed random samples of 75 undergraduate students and 50 graduate students. Subjects reported the hours they sleep in a typical night.For this hypothesis test, he defined the population means as follows:μ 1 is the mean number of hours undergraduate students sleep in a typical night.μ 2 is the mean number of hours graduate students sleep in a typical night.VariablesHours: typical number of hours a student sleeps each nightProgram: undergraduate or graduate Program is the explanatory variable, and the data is categorical. Hours is the response variable, and the data is quantitative.DataDownload the sleep2 (Links to an external site.) datafile, and upload the file in StatCrunch. PromptState the null and alternative hypotheses. Include a clear description of the populations and the variable.Explain why we can safely use the two-sample T-test in this case.Use StatCrunch to carry out the test. (directions)Copy and paste the content of in the StatCrunch output window (text and the table) in your initial post. State a conclusion in the context of this problem.I will attach statcrunch information once bid is selected
