Assuming that the distribution of XYZ stock returns is a population, what is the population standard deviation?A. 5.02%.B. 6.84%.C. 46.22%.D. 8.96%. 正确答案:D 分享到: 答案解析: The population standard deviation, σ, is found by taking the square root of the population variance. 统计...
It gives an algorithm for addition, subtraction, multiplication, division and square root, and requires that implementations produce the same result as that algorithm. Thus, when a program is moved from one machine to another, the results of the basic operations will be the same in every bit ...
Exposure to radiofrequency (RF) electromagnetic fields (EMF), particularly from telecommunications sources, is one of the most common and fastest growing anthropogenic factors on the environment. In many countries, humans are protected from harmful RF EMF exposure by safety standards that are based on...

Whiles the role of job type and personality traits have been well studied, what remains as a gap is the interactions between personality traits in the contexts of different work environments. To address the current gap in the literature on how personality traits interact in predicting passion at...
we found that the temporal frequency of flicker matches the frequency where sensitivity is maximal in a wide range of fish taxa, suggesting that the flicker may actually enhance the detection of objects. Finally, using modeling of the chromatic contrast between fish pattern and background under fli...
I use this device to find compaction layers, or zones. As the probe travels deeper in the soil, it is ordinary for the PSI (pounds per square inch) to increase as pore space decreases. It is important to take note of when the dial stays elevated, and at what depth. When the dial ...
