Now that you have dealt with your cashier Joe, you can turn your attention back to examining how profitable your concession stands are. This past week, several events were held at the venue. Some events were well attended, which resulted in long waiting times for food and beverages. Some events were not well attended, which resulted in no waiting time, so customers were served immediately.

You’ve been wondering whether customers spend more money if they wait longer in line.

The goal of the assignment is to effectively use the formulas and functions to determine if there is a relationship between waiting time and money spent. Complete the following steps:

Run the regression and calculate r.
Interpret the data.
Submit your results.

To run the regression and calculate r, open the STAT 222 The Longer You Wait (XLSX) spreadsheet.Preview the document Column A will contain waiting time in minutes for 20 randomly selected customers. Column B will include the dollars spent by these customers. To populate column A, copy one of the Waiting Times – Random Number Table -1-20 columns (D-I) and paste it into cell A3. To populate column B, copy one of the Dollars Spent – Random Number Table – $2-$40 columns (K-O) and paste it in cell B3.

Once you have the two columns with 20 values each, use these resources to run the regression and include the Pearson’s r correlation coefficient.

Step-by-Step Instructions: Scatter Plot, Trend Line, and Correlation
When you are finished, your spreadsheet should look similar to this one. Remember, your numbers will be different, so your regression line will also be different (either positivity or negatively skewed). We are not looking for the “right number” to an assignment question. The goal of the assignment is to effectively use the formulas and functions of excel to evaluate your data, then interpret the results.

Now evaluate your data and interpret the results. Answer the following questions in a document.

What is Pearson’s r that you calculated, and what does it tell us?
What is the r2 that you calculated, and what does it tell us?
Is this a good model for prediction? Why or why not?
Is there a relationship between waiting time and money spent?

Submit the answers to the questions and your spreadsheet to this assignment.

Report on hypothesis testing and statistics

February 26, 2021 Leave a comment Mathematics and Statistics, Undergraduate

Scenario
You have been hired by your regional real estate company to determine if your regions housing prices and housing square footage are significantly different from those of the national market. The regional sales director has three questions that they want to see addressed in the report:

Are housing prices in your regional market higher than the national market average?
Is the square footage for homes in your region different than the average square footage for homes in the national market?
For your region, what is the range of values for the 95% confidence interval of square footage for homes in your market?
You are given a real estate data set that has houses listed for every county in the United States. In addition, you have been given national statistics and graphs that show the national averages for housing prices and square footage. Your job is to analyze the data, complete the statistical analyses, and provide a report to the regional sales director. You will do so by completing the Project Two Template located in the What to Submit area below.

The topic I choose was Is healthcare a right or a privilege? I chose this topic because with millions of people affected by the coronavirus, initially it was very difficult for citizens to receive testing and the proper healthcare that was needed. With the repeal of the Obama care it left millions of Americas fending for themselves causing the virus to spread. This effected most brown/black and lower income families.

Question: People have different opinions on who should provide services in America. Who do you think should primarily provide?

While my IV will be focused on class.

Respond to the following:

Consider this example of a recurrence relation. A police officer needs to patrol a gated community. He would like to enter the gate, cruise all the streets exactly once, and then leave by the same gate. What information would you need to determine an Euler circuit and a Hamilton circuit?
Create a diagram for each type of circuit and explain the differences.
