o two groups. Each person was given a month's supply of tea bags. For one group, the tea contained the herb mixed with green tea, whereas for the other group, the bags contained only the green tea. Participants were not told which type of tea they had, and were asked to drink one cup of tea per day for a month.

The correct answer is Only (A) and (C) are true

Explanation:

In a study or research, the control group is the one that does not receive a treatment. This means, in this case, the control group includes those who only drink the green tea without the herbs because they serve as a standard to measure the effects of the herbs. This makes statement A (The "only green tea" group serves as the control group) true; also, the group receiving the herbs is the experimental group.

On the other hand, a double-blind study is one in which the researchers and the participants ignore who is receiving the treatment, which guarantees there is objectivity. This occurs in the study presented because neither the researcher nor the subjects known who received the herbal mix. Thus, statement C (This study is double-blind) is true.

Finally, a study is classified as observational if there is not intervention but the researchers just observe participants to study a phenomenon. This does not occur in the study presented because there is an intervention through the herbal treatment, and therefore the study is not observational.

The consumption function shows the relationship between consumption spending and _______. The slope of the consumption function
Stella [2.4K]

Answer:

Consumption Function : Relationship between Consumption Spending & Income

Consumption Function Slope = Marginal Propensity Curve  (MPC)

Change in Consumption = Change in Income X MPC

Explanation:

Consumption Function is the curve representing relationship between Consumption spending and Income.

C = a + bY ; where :- C = Consumption , Y = Income ,  a = Autonomous Consumption i.e consumption at 0 level of income , b = MPC i.e additional consumption consumed from additional income = ΔC / ΔY

b = MPC i.e change in C due to additional change in Y = ΔC / ΔY is the slope of Consumption Function

MPC = ΔC / ΔY .

So, change in consumption i.e ΔC = MPC X ΔY

Ksivusya [100]

Answer:

The correct answer is:

True (A)

Explanation:

Customer access strategy is a framework or a set of standards, guidelines and processes, which defines the means by which a customer and the organization can interact, and  means by which the customer has access to:

  • the relevant information needed to make purchases
  • the right logistics for the execution of a purchase

The arear of access are mainly information (value of the product, price of products, how products work) and logistics (means of getting the products, customer service on the after-purchase needs etc).

It has been studied extensively that companies are spending 3 to 4 times as much money on creating customer access than they do on advertising, this is because even if advertising is successful, the results will not be seen if customer access is not successful, and having an efficient customer access strategy can provide a competitive advantage to the producers.
