Summary Introduction
To think critically about: The example and application of risks into the education domain.
Introduction: The risks arising in a situation are segmented into four criteria’s. Variation risk is something which the organization is prepared for and does not give it much prominence. Foreseen uncertainty is the risk which the organizations have developed contingency plans for. Unforeseen uncertainty is the risk that is not predicted within the limits of organizational strategies. Chaos is also an unforeseen risk which impacts the fundamental goals of the project an organization is working on.

What are epistemic risks and non epistemic risks and examples of each.
An engineer designed a valve that will regulate water pressure on an automobile engine. The engineer designed the valve such that it would produce a mean pressure of 7.2 pounds/square inch. It is believed that the valve performs above the specifications. The valve was tested on 290 engines and the mean pressure was 7.3 pounds/square inch. Assume the standard deviation is known to be 0.6. A level of significance of 0.02 will be used. Determine the decision rule.
Enter the decision rule.

- In 1996, McDonald’s (MD) launched Campaign 55, reducing the prices ofits “flagship” sandwiches with the objective of regaining market share. Beforethe launch, suppose MD’s management envisioned two possible outcomes: astrong customer response or a weak response. Industry experts were notvery optimistic about the campaign. They assessed the probability of a strong response to be .40. MD predicted an expected profit of $50 million if theresponse proved to be strong. If the immediate customer response was weak,management believed that all was not lost. If MD could persuade themajority of its franchisees to back and help fund the campaign, the resultingprofit would be $20 million. However, if the majority rose up against thecampaign, the red ink would fly, and McDonald’s profit would be -$100million. MD considered these two outcomes to be equally likely.a.

The Pepsi-Cola Company conducted the "Pepsi Challenge" by randomly assigning individuals to taste either a Pepsi or a Coke. The researchers labeled the glasses with only an "M" (Pepsi) or a "Q" (Coke) and asked the participants to indicate which they preferred. The research showed that subjects overwhelmingly preferred glass "M" over glass "Q." Why can’t the researchers conclude that Pepsi was preferred to Coke?arrow_forward1.
