What is the confidence interval for 85 percent?
it would be with a level of significance of 0.15.
What is the relationship between levels of confidence and statistical significance?
The connotation 'statistical significance' takes into account the number of samples as well level of confidence in making a conclusion based on these samples. The level of confidence is typically denoted as 1-alpha (1 minus alpha), where alpha is basically the chance that the reported conclusion will incorrect. The most popular level of confidence is 95%, which coincides with a 5% alpha, meaning that when one makes a conclusion based on a particular sample, there is a 5% chance of a false or incorrect conclusion.
If you have a 99 confidence interval what would your confidence level and alpha for it be?
Confidence level 99%, and alpha = 1%.
What confidence level has become the most used or traditional confidence level among business researchers?
95% confidence level is most popular
Difference between p value and level of significance?
P- value is the probability that the given null hypothesis is true and the level of significance is the chance in a hundred or thousand off occurence of an event i an outcome
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".
What is the confidence interval for 85 percent?
it would be with a level of significance of 0.15.
Is The probability at which the null hypothesis can be rejected with confidence is known as level of significance?
Yes.

What is the Probabilities of Critical Statistic?
The standard score associated with a given degree of confidence or level of significance.
If you have a 99 confidence interval what would your confidence level and alpha for it be?
Confidence level 99%, and alpha = 1%.
What confidence level has become the most used or traditional confidence level among business researchers?
95% confidence level is most popular
Find the critical Zc that corresponds to a 98 confidence level?
The 98 percent confidence level is commonly used in statistical tests. The critical Zc refers to the amount of relation between to factors.
What is the timbre of guitar?
Timbre is the quality the sound of a musical note played on an instrument that lets you distinguish a guitar from a Saxophone. At a finer level it lets you distinguish between an Electric Guitar and an acoustic guitar. Finer still, between a good instrument and a poor one.

What happens to the confidence interval if you increase the confidence level?

What is confidence associated with an interval estimate is called the?
confidence level
