Answer and Explanation:
I will go through each and every option explaining the reasons and what option would be the best:
The (a) part says 'difference in wages will eventually disappear since a haircut is a homogeneous good' - This is not true because even though it is an homogeneous product, some customers do have a strong preference for barbers who are not going bald. Therefore, they know their worth and they would want to capitalize on that and get paid just a bit more than bald barbers.
The (b) part says 'barbershops that hire barbers with hair will be able to charge a higher price for a haircut to those consumers who have a strong preference for barbers with hair'. - If the barbershop charges higher price for barbers that have hair then the customers will prefer bald barbers as the questions mentions that there is high competition and since it is an homogeneous, customers would be willing to save money and get their haircut from some other barber.
The (c) part says 'barbershops that hire bald barbers will always be much more profitable' - Not necessarily. The reason is that some customers have a strong preference for barbers who are not bald and therefore, that would help barbershops who have barbers with hair to be a bit more profitable as some additional customers would want their services.
The (d) part says 'barbershops that hire barbers with hair will always be much more profitable' - This is the best option and the reason for it is because some customers have a strong preference for barbers with hair and that would help the barbershop to earn more. They would have the customers who already indifferent to whoever cuts their hair and in addition to that, they would also have the customers who have their preference.
Hence the answer is D.
Answer:
Decrease is taxes
Increase in government spending
Explanation:
Government policies that increases the money supply in an economy is known as expansionary fiscal policy. They are:
1. Decrease is taxes - when government reduces the tax rate, the amount paid as taxes falls and as a result individuals, companies have higher disposable income whuch can be used for consumption or saving. This increases the money supply in the economy.
2. Increase in government spending - if the government increases it's spending on public goods for example, money supply would increase. If the government constructs a road, labour would be employed and paid wages. This payment increases the income of Labour and money supply increases.
Central bank policies that increases money supply are known as expansionary monetary policies. They include:
1. Open market purchase: The central bank purchase securities from the open market to increase money supply.
2. Reduction in reserve requirement ratio : if the reserve requirement ratio is reduced , commercial banks would have more money to give out as loans and this would increase money supply.
Explanation:
To find the probability that the sample which fails to meet the required weight or the standard weight of the marshmallows having banana flavor if the process of production is working, such that probability for the weekly sample leads to shutdown of the production if the process of the production is running properly of 1 % of the probability that at least five boxes out of the twenty five sample fails to meet the standard weight which is less than one percent that is 
We know that for p = 0.8, 
Now using binomial simulation, we can determine that for p = 0.0452
So the production process is to be redesigned for reducing the percentage of boxes of the Go Bananas of 16 ounces which failed to meet the required weight of the marshmallows having banana flavor if the production process is working properly to 5.42 percent.
Answer:
Cualitativa
Dado que están interesados en las razones (las cuales no son una variable numérica), la recopilación de información y la investigación será de tipo cualitativa para poder conocer las razones o motivos por los que la gente ha dejado de comprar.

- La investigación cuantitativa, que se basa en la recolección de datos y variables numéricas y la relación que existe entre ellas.
- La investigación cualitativa, la cual se base en la recolección de datos de tipo no numérico y que no pueden ser medidas con números (por ejemplo opiniones).
En este ejemplo la empresa quiere saber por qué han decrecido sus ventas, dado que están interesados en las razones (las cuales no son una variable numérica), la recopilación de información y la investigación será de tipo cualitativa para poder conocer las razones o motivos por los que la gente ha dejado de comprar.
