A recent study found that the death rate for people who sleep 6 to 7 hours per night is lower than the death rate for people who

sleep 8 or more hours. The 1.1 million observations used for this study came from a random survey of Americans aged 30 to 102. Each survey respondent was tracked for 4 years. The death rate for people sleeping 7 hours was calculated as the ratio of the number of deaths over the span of the study among people sleeping 7 hours to the total number of survey respondents who slept 7 hours. This calculation was then repeated for people sleeping 6​ hours, and so on. Based on this​ summary, would you recommend that Americans who sleep 9 hours per night consider reducing their sleep to 6 or 7 hours if they want to prolong their​ lives

Answer:

Yes, I would recommend those sleeping 9 hours to consider sleeping 6 or 7 hours.

Explanation:

First of all, the sample of the study is very representative because the amount of observations is quite big: 1.1 million!. This means that the results of the study have a very low margin of error, and therefore, can be trusted.

Secondly, the calculations are simple, but correct. The easiest way to determine the mortality rate is to divide the number of people who died by the number of people who are still living, and who belong to the same sample.

Answer:

Allocative efficiency is about distributing or allocating resources in the best possible manner. E.g. in order to fight the current pandemic, more resources ($) is allocated to different health care institutions.

Productive efficiency is about how a company or a person uses the resources that it has in order to produce the greatest amount of benefits at the lowest possible cost. E.g. in a hospital, if a doctor is able to treat 15 patients per day, his/her productive efficiency will be higher than another doctor that only treats 10 patients per day.

All of the following statements about decision style are true EXCEPTA) autocratic styles are authority-based.B) decision styles
notka56 [123]

Answer:

B. decision styles are consistent among top managers

Explanation:

Decision making styles differ between managers.  Many managers exercise autocratic style which is authoritative wherein very limited inputs from the subordinates are taken and there is little scope for constructive advises.

In heuristic style, the strategies help managers to take clear cut decisions in a prompt manner. In such a form, decisions are arrived at quickly.

Managerial decision making methods differ from manager to manager and are an outcome of managers own judgement and demeanor.

Hence it is evident from above points that decision styles are not consistent among top managers.

stich3 [128]

Answer:

c. $900

Explanation:

The computation of the earnings before taxes (EBT) is shown below:

= Sales - operating costs other than depreciation - depreciation expense - outstanding bonds × interest rate

= $10,000 - $7,250 - $1,250 - $8,000 × 7.5%

= $10,000 - $7,250 - $1,250 - $600

= $900

We ignored the state income tax rate of 25% and the rest of the items would be taken for the computation part
