The Tesco case was discussed in the Week 2 Interactive Tutorial. Companies like Tesco gather a massive amount of data through different loyalty card programs. Typically, the shoppers fill out an application form in the shop and receive a plastic card and a key fob* in the mail that is scanned before they make a purchase. In this way, the companies gather massive amounts of data about their customers’ millions of purchases each week. From a company perspective, this is the sales data which plays an essential role in the accounting information system. Then, the data analysts of these companies analyse these sales data and turn it into useful information. Required: a) How can this information be used to get a competitive advantage? [3 Marks] b) What else can these companies accomplish from this collected data? [2 Marks] c) What are the risks associated with these types of loyalty cards? [2 Marks] [7 marks. Word limit: Up to 300 words.] (*Key fob is a small electronic device used typically in place of a key, e.g. to unlock a door or to start a vehicle.)

You are the practice manager for Dermatology Associates of Linwood (DAL): a multi-physician dermatology practice. Recently, the physician partners have decided to invest in purchasing an existing dermatology practice in a neighboring city, which will be operated under the group's name.

The practice is fully-staffed, however the (one) physician owner is retiring, leaving an opening for a new physician to be hired. In keeping with DAL's standard of care, several new expenses will be incurred with the acquisition, including: access to DAL's electronic medical record system, a Fraxel laser, and new furniture for the waiting room area.

______ kind of match type was added as an option on Google’s search ads platform in 2015 because advertisers wanted a middle ground between broad match (which is often too broad for advertisers’ liking) and phrase match (which is often not broad enough). Placing a plus sign in front of a +keyword activates modified broad match. If Bart included “+wakeboard sale” (not including the quotation marks) in his list of keywords, Bart’s ad would show up only for searches that included wakeboard or a close variant, but the term “sale” would allow for broader matches like discount or cheap. If Bart included “+wakeboard +sale” (plus signs in front of both words, not including the quotation marks), his ad would show up for searches using both words, close variants of both words, in any order, and including other words, like wakeboards half price sale and sale on wakebords (misspellings typically count as a close variant).

A. Modified Broad Match

B. Word Type Match

C. Phrase Match

D. Modified Concise

E. None is correct

Let’s consider the phrases at least, at most, less than, more than. Often when we are looking at probabilities, it is phrases like those which are key to translating a word problem into a probabilistic problem. Consider the following statement: The probability that Mary (spends at least, spends at most, spends less than, spends more than) 20 minutes per day exercising. Depending on which phrase you chose in parenthesis you end up with a different expression and meaning in terms of probability theory. For instance, P ( x ≤ 20 ) (probability Mary spends at most 20 minutes exercising) means something different from P ( x > 20 ) (probability Mary spends more than 20 minutes exercising). Write an expression related to your major for each of phrases above and label them with the correct mathematical symbol (use my example as a reference, but I encourage creativity here!). Then explain the differences between the four statements i.e., differences between at least, at most, less than, more than.
