a . The test statistic is -1.160740861

b. The p value is 0.2457473

Let the point estimate be 'a'. The formula for test statistic is:

Z = (a - p) / √ { [ p×(1-p) ]÷n }

Point Estimate 'a' = 30/78 = 0.384615385

Z = (0.384615385 -0.45 ) / √[ (0.45 × 0.55) ] / 78

Z = -0.065384615 / 0.056330071

Z = -1.160740861

Which of the following is an example of the law of diminishing marginal​ returns? A. Holding capital​ constant, when the amount
Irina-Kira [14]

Answer:

The correct answer is option A.

Explanation:

The law of diminishing returns states that as we go on employing more and more unit of input while keeping other inputs constant, the return from each additional unit of input will go on declining.  

This means that the output produced from each additional unit of input will go on declining.

Here, as capital is kept constant and labor is increased by a unit, the output at first increases by 5 units from 20 to 25. But later when input is again increased by a unit, the output increase by only 3 units from 25 to 28.

This shows the law of diminishing marginal returns where the marginal returns from a unit of labor is declining.

According to keynes what should the government do to improve economic conditions during a recession? group of answer choices
Dvinal [7]

Keynesian economics argues that demand drives supply and that healthy economies spend or invest more than they save. To create jobs and boost consumer buying power during a recession, Keynes held that governments should increase spending, even if it means going into debt.

Keynesian economics is a variety of macroeconomic theories and models of how aggregate demand significantly affects economic output and inflation. From a Keynesian perspective, aggregate demand does not necessarily match the economy's capacity. Instead, it is influenced by many factors that affect production, employment, and inflation.

Keynesian economists generally argue that aggregate demand is volatile and unstable, and as a result, market economies often experience inefficient macroeconomic consequences. They further argue that these economic fluctuations can be mitigated through coordinated economic policies between governments and central banks. Fiscal and monetary policy measures, in particular, help stabilize economic output, inflation, and unemployment throughout the business cycle. Keynesian economists generally advocate a regulated market economy. Although primarily the private sector, it plays an active role in government intervention during recessions.
