Why can you never really have 100% confidence of correctly estimating the population characteristic of interest?

Answered by admin AT 14/02/2020 - 05:47 PM

Answer: because you are working with a sample

Explanation: Since you are working with a sample and not all the population, you are generalizing the characteristic to the rest of the people, which can or cannot be accurate. This is way you never have 100% confidence, you are estimating, which is a generalization that can be wrong.

In statistics, especially in social studies, you have a standard error that indicates the accuracy of your estimation. We use the standard error to know exactly how accurate is this sample measurement to the whole population. Also, you have the confidence interval, which indicates you how confident can you be that your estimation is correct.

Which of the following was not a characteristic of the 2010 Haiti earthquake? A. There was a loss of electricity and water. B. The quake hit the capital city. C. The quake registered at 7.8 on the Richter scale. D. The death toll was less than 1,000.

Both C and D answers show uncorrect statements about the 2010 Haiti earthquake.

Answer C states that the quake registered at 7.8 on the Richter scale, but that's not true. The earthquake occurred inland on January 12, 2010, approximately 15 km southwest of Port-au-Prince and at a depth of 10 km at 16:53 local time. It recorded 7.0 on the Richter scale.

Answer D affirms that the death toll was less than 1,000, but this is also incorrect. The effects caused on this country were devastating. The bodies recovered on January 25 exceeded 150,000, calculating that the death toll would exceed 200,000. The final data of those affected were released by Prime Minister Jean-Max Bellerive on the first anniversary of the earthquake, the January 12, 2011, stating that 316,000 people died in the earthquake, 350,000 more were injured, and more than 1.5 million people were left homeless.

Country A has an absolute command economy. Country B has a mixed economy and a population that favors market trade. Both want to increase trade to generate more wealth. Which action would Country B most likely take that Country A would not? Impose stricter divisions of labor Increase production quotas Loosen certain trade regulation Permit limited private ventures

Let's look at all the options in turn:
Impose stricter divisions of labor
-this doesn't have anything to do with trade, so it's not the correct answer.

Increase production quotas
-what we want is a bigger trade, not production, so again, not the correct answer

Loosen certain trade regulation
-this is the best answer. Loosening trade regulations will increase trade, but country A won't do it since it would challenge their control over the market

Permit limited private ventures

-in country B those are likely already permitted anyway
