How many standard deviations above or below the mean should a score be to establish significance?
It depends on the significance level required. And that, in turn, will depend on the cost of making the wrong decision. For ordinary use, a 95% significance level will require 1.96 sd
What is another name for the probability of observing a sample value at least as extreme as a given on under a null hypothesis?
The significance level of the observation - under the null hypothesis. The significance level of the observation - under the null hypothesis. The significance level of the observation - under the null hypothesis. The significance level of the observation - under the null hypothesis.
What is the p-value if 0.01 is the level of significance and the mean is 18688 and the standard deviation is 15500?
In order to solve this you need the null hypothesis value also level of significance only helps you decide whether or not to reject the null hypothesis, is the p-value is above this then you do not reject the null hypothesis, if it is below you reject the null hypothesis Level of significance has nothing to do with the math
How can you explain the significance level of at statistics?
Significance Level (Alpha Level): If the level is set a .05, it means the statistician is acknowledging that there is a 5% chance the results of the findings will lead them to an incorrect conclusion.
How much is a billion in England?
The English use is for a billion to mean 1 000 000 000 000 but this is going out-of-date. While this was common fifty years ago, most people in England now use the American usage and mean 1 000 000 000

Why is the sample standard deviation used to derive the standard error of the mean?
the sample mean is used to derive the significance level.

Are all scientific hypotheses tested at 1 level of significance?
No, not all scientific hypotheses which are tested at level 1 are of significance.

What is the standard form of 10 000 000 000 000 000?
If you mean as in scientific notation then it is: 1.0*10^16

Confidence level and significance level?
I have always been careless about the use of the terms "significance level" and "confidence level", in the sense of whether I say I am using a 5% significance level or a 5% confidence level in a statistical test. I would use either one in conversation to mean that if the test were repeated 100 times, my best estimate would be that the test would wrongly reject the null hypothesis 5 times even if the null hypothesis were true. (On the other hand, a 95% confidence interval would be one which we'd expect to contain the true level with probability .95.) I see, though, that web definitions always would have me say that I reject the null at the 5% significance level or with a 95% confidence level. Dismayed, I tried looking up economics articles to see if my usage was entirely idiosyncratic. I found that I was half wrong. Searching over the American Economic Review for 1980-2003 for "5-percent confidence level" and similar terms, I found: 2 cases of 95-percent significance level 27 cases of 5% significance level 4 cases of 10% confidence level 6 cases of 90% confidence level Thus, the web definition is what economists use about 97% of the time for significance level, and about 60% of the time for confidence level. Moreover, most economists use "significance level" for tests, not "confidence level".
