This is binomial
distribution problem. <span>
We are given that:</span>
n = sample size = 500
p = proportion which
burns wood = 0.27,
q = proportion which
does not burn wood = 1-p = 0.73
<span>
A. Mean is calculated as:</span>
Mean = n*p
Mean = 500 * 0.27
Mean = 135
<span>
B. Variance is calculated as:</span>
Variance = n*p*q
Variance = 500*0.27*0.73
Variance = 98.55
<span>
C. Standard deviation is calculated as:</span>
Standard deviation = sqrt(variance)
Standard deviation =
sqrt(98.55)
<span>Standard deviation =
9.93</span>

Answer: a. increased
Explanation:
Inflation rate = (CPI of second year - CPI of the first year ) / CPI of the first year
= (240 - 238) / 238
= 0.84%
Your wage increased by 3.5% which is more than inflation so your real wage increased by;
= 3.5 - 0.84
= 2.66%
Answer:
The correct answer is: firms are unlikely to undertake investment.
Explanation:
The liquidity trap is a situation described in the Keynesian economy according to which, liquidity injections into the private banking system by the central bank do not lower interest rates or inject money into the economy and therefore do not stimulate economic growth as claimed by monetarism.
The liquidity trap occurs when people accumulate cash because they expect an adverse event, such as deflation, reduction in aggregate demand and GDP, an increase in the unemployment rate or a war. People are not buying, companies are not borrowing and banks are not lending either because they do not have enough solvency since the economic outlook is uncertain and investors do not invest because the expected returns on investments are low.
The most common characteristics of a liquidity trap are interest rates close to zero and fluctuations in the monetary base that do not translate into fluctuations in general price levels.
Answer:
B). Response bias
D). The interviewer should reword the question.
Explanation:
Response bias is described as the type of bias in which a variety of tendencies are displayed by the respondents to answer the questions asked in the survey inaccurately or misleadingly. These false responses eventually lead to a false or deceiving conclusion. In the given survey, 'response bias' is displayed as the respondents may display a tendency to answer the question falsely as the feeling of 'patriotism' evoked by the word 'patriotic' may prevent their original opinions to come out. Thus, <u>option B</u> is the correct answer to describe the bias in this survey.
In order to prevent this bias, the interviewer must 'reword the question' and remove the word 'patriotic' as it develops the feeling of patriotism in the respondents which mars them from answering accurately and share their true opinions or thoughts in the regards of 'supporting armed forces.' This rewording will help evoke the true and authentic responses without any bias. Thus, <u>option D</u> is the correct answer to remedy the bias.
