MAT 144 GCU Calculate Gain & Loss of Value for Stock as Of Each Date Excel Template
Hi Class,This should be sort of fun, see how much money you can make … or lose! Start by downloading the attached template.The video “Tech Hints QR 2-7” in the media resources section of the eBook covers the calculations you’ll be doing for this DQ. (Our template does look a little different, but it is essentially the same.)Here is a video I made to help: https://youtu.be/iSMKu1B1fVc Here are specific instructions for completing the DQ:In the initial investment section (A1:F4), select three different stocks to track. Select your stocks from the New York Stock Exchange listings directory at https://www.nyse.com/listings_directory/stock. Use the “Filter” text box to search for specific stocks; click on the stock Symbol in the list at the right to go to the stock quote page for the stock to see more details, including historical prices. Towards the bottom, you can find a chart that will let you input date ranges. You can input the same date for start and end to look up your specific day.Use a purchase date of 1 year ago, for each stock. So if it is Feb 18, 2020, then you look at the price Feb 18, 2019. Find each stock’s price on that date and enter it into the Price per Share field. The table does not contain data points for weekends. If your date is on a non-business day choose a date close to your date listed. Assume that the number of shares purchased is 100 for your first stock, 200 for your second stock, and 300 for your third stock and that the fees are $5, $10, and $15 (total fee) for your first, second, and third stocks. Enter an appropriate formula in the Initial Investment field, and calculate an initial investment total in cell F5.In cells A14:F16, continue your analysis for your first stock. Use the closing price 9 months ago, 6 months ago, 3 months ago, and the latest for the second through fifth date sections. Just get close to these dates, basically, we are looking at quarterly fluctuations. Look up the closing price per share on each of these dates and enter those in column D. Calculate a current value on each date in column E. Calculate the gain or loss to date (starting from the initial purchase date) in column F.Repeat the analysis from step 3 for your second and third stocks, using cells H14:M16 for the second stock and O14:T16 for your third stock.In column V, calculate (in cells V14:V16) the total gain or loss for all three stocks on each of the three dates.Hint: To get the stock value on a particular date from the stock quote page, scroll down to the stock chart or stock table below it.Hi Class,I made a video to help with the website.

HLTH 501 Medical Advertising and Biostatistics discussion
Goods
and services of all kinds are advertised to potential customers to
expand product usage and to make profits. Medications are advertised as
well. If they were not, people would be unaware of the products
available to them and sales may be so low that no money is made by the
companies who have invested in the new medication. When
reading or hearing about drugs and medical treatments, especially new
products, the source of the information is important. Also, all drugs
and treatments have positives and negatives, so hearing a few positive
(or negative) soundbites might not give a person the information they
need to decide if the drug is right for their situation. Statistics
are often used when medications are advertised to the general public.
Yet do most people understand what the risks and benefits are? How good
is the statistical knowledge of the general population? Is it easy to
think clearly and analytically when sick, weak, or in pain? Take
this example. Which drug would you rather take: One that reduces your
risk of cancer by 50 percent, or another drug that only eliminates
cancer in one out of 100 people? Most people would choose the drug that
reduces their risk of cancer by 50 percent, but the fact is, both of
these numbers refer to the same drug. They’re just two different ways of
looking at the same statistic. One way is called relative risk; the
other way is absolute risk. Here's how it works: Let’s say
there is a trial involving 100 people. Two people would normally get
breast cancer during the trial duration, but when all 100 people are put
on the drug, only one person gets breast cancer. This means the
reduction of breast cancer is one person out of 100. Yet the relative
risk reduction is 50 percent because one is 50 percent of two. In other
words, the risk is cut in half from a relative point of view. Even
though this drug may help one out of 100 people, its side effects
create increased risks to all 100 people. Everyone suffers some harm
from the potential side effects of the drug, even if that harm is not
immediately evident. However, only one out of 100 people was actually
helped by the drug. Review the 10 Essential Services of Public Health here: https://www.cdc.gov/stltpublichealth/publichealthservices/essentialhealthservices.html In your post: Discuss how 4 of the Essential Services of Public Health relate to the issues of medication advertising and biostatistics. How would you rate your statistical knowledge? The knowledge of an average U.S. resident?Do
you think statistics should be used when advertising new medications?
How can advertisers help ensure that the stats they are using do not
oversimplify or give only a partial picture of the risks involved? Cite at least one scripture passage that pertains to this topic. Your thread is due by 11:59 p.m. (ET) on Thursday and your two replies are due by 11:59 p.m. (ET) on Sunday.
