The accuracy of predictive analysis is intricately linked to the currency of its data. Temporal factors play a pivotal role in the precision of predictions. Data from a year past might prove too antiquated to effectively forecast trends and patterns in today's dynamic global market. Neglecting this temporal dimension could potentially expose organizations to substantial financial risks.
The American Association of Individual Investors conducts a weekly survey of its members to measure the percent who are bullish, bearish, and neutral on the stock market for the next six months. For
the week ending November 7, 2012 the survey results showed 38.5% bullish, 21.6% neutral, and 39.9% bearish (AAII website, November 12, 2012). Assume these results are based on a sample of
300 AAII members.
a. Over the long-term, the proportion of bullish AAII members is .39. Conduct a hypothesis test at the 5% level of significance to see if the current sample results show that bullish sentiment differs
from its long-term average of .39. What are your findings?

- Paraphrase this one. Analyze and elaborate in 120 words. Predictive analytics involves a statistical approach called regression, which helps us uncover connections between different factors. This technique is valuable for spotting trends within extensive sets of information and figuring out how various inputs relate to each other. It shines brightest when dealing with continuous information that follows an established pattern. Regression frequently comes into play when we want to understand the impact of one or more independent factors on another. For instance, it aids in grasping the effect of raising prices on product sales. This tool holds the key to unraveling hidden insights in data that might otherwise remain unnoticed.arrow_forwardNote:- Do not provide handwritten solution.

And yet, sometimes correlation is used. For example, in car insurance, male drivers are correlated with more accidents, so insurance companies charge them more. It would be impossible to actually test this for causation. Given the above, how do we balance this possibility of error with the need to have statistical results to inform our business decisions?arrow_forward

The strong form efficient market hypothesis a) I, II, and III b) I and II c) I d) None of I, II, and IIIarrow_forwardWhich of the following statements is CORRECT regarding risk and return? Group of answer choices: A stock's market risk is more relevant to an investor with a well-diversified portfolio than to an investor who holds only that one stock. It is impossible to have a situation where the market risk of a single stock is less than that of a portfolio that includes the stock. The higher the correlation between the stocks in a portfolio, the lower the risk inherent in the portfolio. An investor can eliminate virtually all market risk if he or she holds a very large and well diversified portfolio of stocks. Once a portfolio has about 40 stocks, adding additional stocks will not reduce its risk by even a small amount.arrow_forwardWhen comparing the Lexis and Westlaw legal research platforms, which of the following statements is true? Lexis is a better legal research platform than Westlaw and is the preferable legal research search engine. A search performed on Lexis should produce the same results as a search performed on Westlaw. Westlaw requires researchers to complete more trainings and certifications than Lexis. Lawyers use Westlaw, and paralegals use Lexis.arrow_forward
- You are a new salesperson at a large software manufacturing firm. It is three weeks from the end of the sales quarter and you and your sales manager have both already met your sales quotas for the quarter. In addition, you just closed another deal with a new customer for $100,000 worth of software and customer service. This order would put you way over your sales quota for the current quarter. Your manager suggests that you hold this new order so it gets recorded against next quarter. She explains that because sales during the next three months tend to slow down, salespeople frequently miss their quotas and associated sales bonuses for that quarter. Holding this large order to next quarter would help you get an excellent start and almost guarantee that you meet your quota. What would you do?arrow_forwardYou are the general manager of a luxury car dealership. You are considering purchasing data from a data broker that collects data of high potential value to your dealership. In addition to providing a list of names, mailing addresses, and email addresses, the data include an approximate estimate of individuals’ annual income based on the zip code in which they live, census data, and highest level of education achieved. Using the data provided by the broker, you could establish an estimated annual income for each person on the list to identify likely purchasers of your dealership’s autos and then send emails to those potential customers. List the advantages and disadvantages of such a marketing strategy. Would you recommend this means of promotion in this instance? Why or why not?arrow_forwardSuppose that you work at a local food manufacturer and are given the task of investigating your company's seasonal sales patterns over the past 10 years (2011 to 2020).
