Purdue University Global Business Statistics and Quantitative Analysis
Topic: Is this Normal?One theory about the daily changes in the closing price of a stock is that these changes follow a random walk – that is, these daily events are independent of each other and move upward or downward in a random manner – and can be approximated by a normal distribution. To test this theory, collect the most recent closing prices of stocks from for your favorite company or brand. You can find this by going to finance.yahoo.com and searching for “Your Company stock history.” See Example and DB starter video in Unit 4 LiveBinder.Must be original content/response.Main Post:1) Choose your favorite company or brand and search finance.yahoo.com with that company name and “historical stock prices”. Download the stock history for this company for the past 6 weeks by selecting the appropriate dates and clicking on “Download to Spreadsheet” at the bottom of page.2) Calculate the daily change in the closing stock prices by taking the difference between the closing and opening price for the day. This is the daily stock change.3) Run the Descriptive Statistics->Summary Table in Excel Data Analysis on the daily stock change. Share the summary table.4) Calculate the 1st and 3rd quartiles of the daily stock change. Share these along with the min, median, and max from 3) as your 5-Number Summary.5) Create a Box & Whiskers Plot using your 5-Number Summary. (For Help, refer to Unit 2 LiveBinder).6) Is your daily stock change distribution right skewed (median < mean), left skewed (mean < median), or symmetric (mean ≈ median)? Would you consider your daily stock change to be normally distributed? Why or Why Not?

Math 980 quiz
One application of 'Linear Equations' is the concept of the relationship between the distance traveled, the rate of travel and the time traveled. Under the assumption that the rate is constant, the relationship becomes the formula: distance = rate x time. (D = RT)
1.Suppose the distance in miles traveled from home to school is 15 miles. Suppose this distance can be travelled in 36 minutes. Find the time in hours travelled from home to school. The minutes can be divided by 60 to get hours. For example 45 minutes = 45/60 = 0.75 hours. Write the answer at a number only with a zero before the decimal, i.e. 0.75.
2.You have found a new route to school that is 12 miles. You can drive the new route in 0.4 hours. Using D=RT, insert the D and T values into this formula and write the resulting equation. Leave NO spaces in the answer. Leave the units out of the equation. Example: 12=0.75R
3.Solve the equation in Question 2 which represents the average speed. Write the answer by filling in the blank. R = _____mph
4.Suppose you need to drive the 'new' route to school in 15 minutes. Using D=RT, insert your D value and the new T value into this formula and write the resulting equation. Fifteen minutes will have to be converted to hours. Leave NO spaces in the answer. Leave the units out of the equation. Example: 12=0.75R
5.Solve the equation in Question 4 which represents the average speed. Write the answer by filling in the blank. R = _____mph
6.Suppose you were traveling the 'new' route to school at 40 mph. Using D=RT, insert your D value and the new R value into this formula and write the resulting equation. Leave NO spaces in the answer. Leave the units out of the equation. Example: 12=15T
7.Solve the equation in Question 6, in minutes, which represents the time traveled. Time in hours will have to be converted to minutes. Write the answer by filling in the blank. T = _____minutes

RSCH 8210 Walden University Calculate Confidence Interval Task
To prepare for this Assignment:
Review the Learning Resources related to probability, sampling distributions, and confidence intervals.
Using the SPSS software, open the Afrobarometer dataset or the High School Longitudinal Study dataset (whichever you chose) from Week 2.
Choose an appropriate variable from Weeks 2 and 3 and calculate a confidence interval in SPSS.
Once you perform your confidence interval, review Chapter 5 and 11 of the Wagner text to understand how to copy and paste your output into your Word document.
For this
Write a analysis of your results and include a copy and paste of the appropriate visual display of the data into your document.

Project Week 7Using the ROI data set: For each of the two majors: Draw the scatter diagram of Y = ‘Annual % ROI’ against X = ‘Cost’.Obtain b0 and b1 of the regression equation defined as y ̂ =
b0 + b1X and the coefficient of determination (r2) from the Excel
regression output. Draw the fitted regression line on the scatter diagram.Calculate the estimated ‘Annual % ROI’ when the ‘Cost’ (X) is $160,000.Test the hypothesis:
H0: β1 = 0Ha: β1 ≠ 0 Write a paragraph or more on any observations you make about
the regression estimates, coefficient of determination, the plots, and
the results of your hypothesis tests.Data attached
