背景情况:
- 野生捕捞的鱼是全球主要的粮食和料来源,在2000-2019年期间,年平均捕捞量为7700万.
- 与其他脊椎动物不同,捕捞鱼的量度是生物质,而不是个体数量,尽管承认鱼类的感知能力.
研究的目的:
- 估计2000-2019年间每年全球野生捕捞的鱼类数量.
- 倡导以数量而不是生物质来报告捕捞的鱼类.
- 为解决野生捕捞鱼类的福利问题.
主要方法:
- 粮食及农业组织 (FAO) 使用的捕捞产量 (着陆) 位 (2000-2019年).
- 综合估计捕捞时平均个体鱼的重量,从互联网来源的数据.
- 根据位和平均个体重量计算的年度全球鱼数量.
主要成果:
- 据估计,在2000年至2019年期间,平均每年捕获1.1-2.2万亿个 (1.1-2.2 × 1012) 野生鱼.

As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

01:11Testing a Claim about Mean: Known Population SD
2.7K
A complete procedure of testing the hypothesis about a population mean is explained here.
Estimating a population mean requires the samples to be distributed normally. The data should be collected from the randomly selected samples having no sampling bias. The sample size needed to be higher than 30, and most importantly, the population standard deviation should be already known.
In most realistic situations, the population standard deviation is often unknown, but in rare circumstances, when it...
