For example, view Walmart's Financial Information: Annual Reports & Proxies (Links to an external site.)

page to the find the comparable store sales for Walmart. Note: The Walmart Financial Information page is just an example. You will need to find your own company to research, searching for the most recent data.

In your post, examine three different data points from the data set. Be sure to include the URL of the website you are considering.

For the data points you selected, address each of the following:

Indicate the name of the data for each data point and the information associated with the data. Copy and paste the three selected data points in your post.

Explain whether the variable is cross-sectional or time series.

Explain whether the type is quantitative or categorical. If quantitative, give the unit of measurement.

What are the important factors in the dataset? How would you plan to handle the missing data if there are some in the report?

Explain the value of the data. Who might find this useful? Why?

(Question 3) 1. Load the data "mtcars" 2. Run the following code. scatterplot3d (wt , disp, mpg , pch=16, highlight . 3d=TRUE, type="h" , main="3DScatterplot") Interpret "pch=16" and "highlight.3d=TRUE" in this code. 3. Plot scatterplot matrices among factors: mpg, cyl and wt. 3 4. Plot barplot with both factors gear and cyl under the title "Cars by gear and cylinder" 5. Plot boxplot of qsec by cyl with title "Speed test".Consider three urns, one colored red, one white, and one blue. The red urn contains 1 red and 4 blue balls; the white urn contains 3 white balls, 2 red balls, and 2 blue balls; the blue urn contains 4 white balls, 3 red balls, and 2 blue balls. At the initial stage, a ball is randomly selected from the urn whose color is the same as that of the ball previously selected and is then returned to that urn. Let X,, be the color of the ball in the ath draw. (a) What is the state space? (b) Construct the transition matrix P for the Markov chain. (c) Is the Markove chain irreducible? Aperiodic? (d) Compute the limiting distribution of the Markov chain. (Use your computer) (e) Find the stationary distribution for the Markov chain. (f) In the long run, what proportion of the selected balls are red? What proportion are white? What proportion are blue?3 Question 97/100 Attempts Correct Antibodies are composed of two types of peptides, heavy chains and light chains.
