Answer:
The correct option is D) The design of the study suffers from selection bias.
Explanation:
In research, Selection Bias occurs when the researcher decides who the respondents are or those who are being evaluated or studied.
Every research ought to be designed in such a way that the respondents are selected at random.
In the information provided, the respondents were selected from a group of people who on a balance of probability were already inclined to decline because it was a list of dissatisfied customers. The chances of them declining to respond or responding with a negative were higher than the chances of them indicating that they would buy and this defeats the purpose of the research. The research ought to have also included a sample of respondents who didn't have the product, who had enjoyed the services of the company and were content, those who didn't even know what the product did until they got the survey.
That way holistic information can be obtained from the research about how different sets of people will react and not just those who are already dissatisfied with the company's product(s).
Some of the ways to avoid selection bias in research are:
- To employ the use of random techniques selecting sample sets from populations.
- To check that the traits or characteristics of the larger population are well represented in the samples selected

Exchange rates are an effective way to analyze the price of one currency in terms of another currency with the tools of demand and supply.
<h3>What do you mean by exchange rate?</h3>
Exchange rates refer to the value of one's nation's currency over the currency of another nation.
An exchange rate can be fixed or free-floating. A fixed exchange rate is pegged to the value of other currency and a free-floating exchange rate may rise or fall due to changes in the foreign exchange market.
Thus, exchange rates are an effective way to analyze the price of one currency in terms of another currency with the tools of demand and supply.

Answer:
private saving = $2700
Explanation:
given data
GDP = $10,000
Consumption = $6,000
Government spending = $1,500
deficit = $200
solution
we know here equation of GDP that is express as
GDP = Consumption + investment + Government spending ...................1
we consider here tax revenue that is = T
T - Government spending = - deficit
T = Government spending - deficit
T = $1500 - $200
T = $1300
so we can say from equation 1
( GDP - Consumption - T ) + ( T - Government spending ) = investment
and investment = private saving + public saving
so private saving will be
private saving = GDP - Consumption - tax revenue ................2
private saving = $10000 - $6000 - $1300
private saving = $2700
Answer:
Explanation:
Production budget is a schedule of the number of units of goods that are to be produced using a forecast sales amount and the level of the opening and closing inventory
Bath Scale Gym Scale
Northern region 25,500 33,300
Southern region 27,500 28,900
Total 53,000 62,200
Opening inventory (1,200) ( 2,500 )
Closing inventory 900 2,700
Total units to be produced 52,700 62,400
Bath scale = 53000+900 -1200 = 52700
Gym scale = 62200+ 2700-2500 =62,400
