What are the alpha and the confidence level for a 90 percent confidence interval?
For a 90 percent confidence interval, the alpha (α) level is 0.10, which represents the total probability of making a Type I error. This means that there is a 10% chance that the true population parameter lies outside the interval. The confidence level of 90% indicates that if the same sampling procedure were repeated multiple times, approximately 90% of the constructed intervals would contain the true parameter.
What would happen to the width of the confidence interval if the level of confidence is lowered from 95 percent to 90 percent?
decrease
F-statistic significant at a 95 percent or greater confidence level?
The user selects the confidence level. It could also be 90 or 99 or 99.9 or another value.
What is the confidence level for a confidence interval of 46.8 to 47.2?
The confidence level for a confidence interval cannot be determined solely from the interval itself (46.8 to 47.2) without additional context, such as the sample size or the standard deviation of the data. Typically, confidence levels (e.g., 90%, 95%, or 99%) are established based on the statistical method used to calculate the interval. To find the exact confidence level, more information about the underlying statistical analysis is needed.
If you have a 99 confidence interval what would your confidence level and alpha for it be?
Confidence level 99%, and alpha = 1%.

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
What happens to the confidence interval if you increase the confidence level?
The confidence interval becomes wider.
What is a measurement of an argument strength where the higher the confidence level the more likely the conclusion is true?
Confidence level is a statistical measure that indicates the likelihood that a conclusion is true. It is expressed as a percentage, where a higher confidence level indicates a greater probability that the conclusion is accurate. A confidence level of 95%, for example, suggests that there is a 95% chance that the conclusion is true.
What is confidence associated with an interval estimate is called the?
confidence level
This is a measurement of an arguments strength where the higher the confidence level the more likely the conclusion is true?

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".
