What is the sample size would you need for a 95% confidence interval to have a margin of error of no more than 0.45? Estimating Sample Size Estimation of the sample size for the one-sample mean is a function of population standard deviation, ...
The unit to be used is calledStandard Error. It’s labeled “Standard” because it serves as a standard unit. And it’s labelled “Error” because we don’t expect oursample statisticvalues to be exactly equal to the populationparameter; there will be some amount of erro...
In fact, the Abell catalogue is used as a starting point for astronomers who study these objects. One of the reasons his scheme has been so widely accepted is because of his sample size. With all the clusters in his sample, he could determine the different characteristics of clusters. ...
What is life? Like most great questions this one is easy to ask but difficult to answer. The reason is simple: we know of just one type of life and it’s challenging to do science with a sample size of one. The field of artificial life-called ALife for short — is the systematic a...

Answer to: What is the relationship between sample size (replication), precision among data values, error bar size, and confidence in results? By...
with a sample size of one. The field of artificial life – called ALife for short – is the systematic attempt to spell out life’s fundamental principles. Many of these practitioners, so-called ALifers, think that somehow making life is the surest way to really understand what life is. ...
A reader asked me about this special case. Production of 500,000 pieces is underway. An inspection is done when 10% of the production is ready. With a normal inspection level II, what is the sample size? 800 because total production is 500,000?
Curve fashion “generally is for people that have more of a pear body shape,” Keist said, clarifying that “bodyshapeis not bodysize.” “My hips are the widest part of my body,” she added. “So the curve is to accommodate — especially in pants — where the hip is wider than wh...
Earth is the planet of life. Running, crawling or flying, life abounds everywhere.地球是一个满是生命的星球。奔跑着的、爬行着的或飞翔着的，到处都是生命。But for all this beautiful diversity to have proliferated, Earth has had to provide a favourable environment for around four billion years. ...
