Answer:

Explanation:

Experiments were performed for 240 people, 60 people test positive.

Step 1: we calculate the sample proportion; p= 60/240= 0.25.

Step 2: calculate the standard error for the sample, which is the square root of sample proportion,p = p(1-p)/n, n=100

0.25(1-0.25)/100

= 0.04.

Step 3: calculate the test statistics; assuming the hypothesis test percentage is 25%

Then, we say 0.25-1=0.75

-0.75/0.04

= -1.875.

In particular, the sample results are -1.875 standard error.

Probability of Z is less than -1.875.

Look up it value in the Z table

All of the following would affect the position of the supply curve for cranberries, except: Question 28 options: the price of ag
myrzilka [38]

The factor that would not affect the position of the supply curve for cranberries is the popularity of cranberry drinks.

The supply curve is a graph that shows the relationship between price and the quantity supplied. The supply curve is positively sloped. A change in the position of the supply curve can either be an outward shift or an inward shift. An outward shift indicate an increase in supply and an inward shift indicates a decrease in supply.

An increase in the price of agricultural land and the cost of fertilizers increases the cost of producing cranberries . This would lead to an inward shift of the supply curve. On the other hand, a decrease in the price of  agricultural land and the cost of fertilizers would lead to an outward shift of the supply curve.

The development of a new pest control for cranberry production would lead  to an outward shift of the supply curve as more cranberries can be produced.

Please check the attached image for a graph showing an increase in supply. To learn more about the supply curve, please check: brainly.com/question/1915798

An economy is operating with output $400 billion above its natural level, and fiscal policymakers want to close this expansionar
antoniya [11.8K]

Answer: reduced by $80 billion

Explanation:

An expansionary gap is when the actual output is more than the potential output. From the question, we are told that an economy is operating with output $400 billion above its natural level, and fiscal policymakers want to close this expansionary gap and that the central bank agrees to adjust the money supply to hold the interest rate constant, so there is no crowding out.

We are also given the marginal propensity to consume is 4/5, and told that the price level is completely fixed in the short run.

To close the expansionary gap, the government would need to reduce its spending. To solve this, we have to calculate the multiplier. This will be:

Multiplier = 1/(1 - MPC)

= 1/(1 - 4/5)

= 1/1-0.8

= 1/0.2

= 5

Therefore, the government expenditure or spending will be reduced by:

= $400 billion/5

=$80 billion

True/False: the two most common means of acquisition are the entrepreneur's direct purchase of the firm's entire stock or assets
Neporo4naja [7]

Answer:

True

Explanation:

According to Thomas Duening and Robert Hisrich book "Technology Entrepreneurship: Taking Innovation to the Marketplace", the direct purchase has some problems: long-term capital gain to the seller and double taxation. The bootstrap purchase eliminates those problems: the acquiring company can acquire a small amount of the firm, 20 or 30% in cash and the remaining with a long-term note.
