Ellie is an internal Consumer Insights researcher for JumpBab, a company that makes children's game Apps for smart devices. In her research of marketing trends, she observes that the downloads for her Apps is positively related to the per capita consumption of goat cheese; and negatively related to the number of engine failures of Ford Fiesta cars in the USA. Excited at finding these interesting relationships between these variables, she declares to her Marketing Manager that "JumpBab should include mentions goat cheese in all our marketing communications, but really stay away from Ford Fiesta cars!" Despite the statistical soundness of the data, Ellie's Marketing manager scoffs at her suggestion. This is likely because:

a. Ellie has most likely tapped into an illusionary correlation in her data.

Explanation:

Illusionary Correlation is a phenomenon in Psychology and Statistics where during the course of research, the researcher perceives a relationship to exist between the variables due to seemingly statistically significant findings when no such relationship actually exists.

The problem is that since such correlations are usually rare, they are easier to discover and fixate on.

The likelihood of children apps being influenced by goat cheese and the number of engine failures of Ford Fiesta cars in the USA would make quite a number of people scoff which is why her manager was skeptical.

Answer from: Quest

sound is invisible, but sometimes we can feel it. when a kettle-drum is thumped with a stick that time the tight drum skin moving up and down very quickly for some time and then it pumped sound waves into the air. loudspeakers also work in a similar manner.

components of a speaker:

electromagnet

in order to translate an electrical signal into an audible sound, an electromagnet is used in looudspeakers

suspension

suspension is used to center the voice coil in the gap of the magnet and it exerts a restoring force to keep it there. suspension is used to limits the maximum mechanical excursion of the diaphragm and voice coil.

voice coil

voice coil is a coil of wire which is attached to the apex of a loudspeaker cone. it provides the motive force to the cone by the reaction of a magnetic field to the current passing through it.

cone

in a loudspeaker, a thin, semi-rigid membrane attached to the voice coil, which moves in a magnetic gap due to which it vibrates and produced sound. it is known as diaphragm and it can also be called a cone, though not all speaker diaphragms are cone-shaped.

surround

surround is also known as front suspension. surround is used to join the cone to the chassis. together with the suspension it controls the cone excursion, and it is also used to determine how energy which is travelling through the cone is absorbed, and how the speaker limits when it reaches the ends of its travel.

dustcap

dustcap is used to protect the voice coil from dust and dirt. it is a part of the cone.

how speaker work

the outer part of the cone is fastened to the outer part of the loudspeaker's circular metal rim. the inner part is fixed to voice coil that sits just in front of a permanent magnet . when loudspeaker is hooked up to a stereo, electrical signals feed through the speaker cables into the coil. it will convert the coil into an electromagnet magnet . when electricity flows back and forth in the cables, the electromagnet either repels or attract the permanent magnet. this moves the coil back and forth, and it pull and push the loudspeaker cone. like a drum skin vibrating back and forth, the moving cone pumps sounds out into the air.in this way loudspeakers works.

administrative jobs normally have someone answering phone calls and scheduling appointments, filing patient or customer information, making sure the front of the office looks nice to those who enter the building. administrative jobs can also include making sure the manager has everything they need for meetings, making delivers and much more. administrative jobs are important to most businesses as are customer service focused as they are often one of the first impressions a consumer sees of a business.

Consider how health insurance affects the quantity of health care services performed. suppose that the typical medical procedure has a cost of $160, yet a person with health insurance pays only $40 out of pocket. her insurance company pays the remaining $120. (the insurance company recoups the $120 through premiums, but the premium a person pays does not depend on how many procedures that person chooses to undergo.) consider the following demand curve in the market for medical care. use the black point (plus symbol) to indicate the quantity of procedures demanded if each procedure has a price of $160. then use the grey point (star symbol) to indicate the quantity of procedures demanded if each procedure has a price of $40. q d at p=$160 q d at p=$40 0 10 20 30 40 50 60 70 80 90 100 200 180 160 140 120 100 80 60 40 20 0 price of medical procedures quantity of medical procedures demand if the cost of each procedure to society is truly $160, the quantity that maximizes total surplus is procedures. economists often blame the health insurance system for excessive use of medical care. given your analysis, the use of care might be viewed as excessive because consumers get procedures whose value is than the cost of producing them.
