For some tests, such as the Fisher F-test, the test statistic is an estimate of the variance. If the alpha level was not affected, the test would be no use at all!

How do sample size confidence level and standard deviation affect the margin of error?

What does standard deviation help you find?
Standard deviation helps you identify the relative level of variation from the mean or equation approximating the relationship in the data set. In a normal distribution 1 standard deviation left or right of the mean = 68.2% of the data 2 standard deviations left or right of the mean = 95.4% of the data 3 standard deviations left or right of the mean = 99.6% of the data
What combination of factors will increase the chances of rejecting the null hypothesis?
a small standard error and a large alpha level
Will standard deviation come up on the examination paper?
It can do. Depends on which subject, at which level, in which country. But since you have chosen not to share those relevant bits of information, your question cannot be answered.
If you have a 99 confidence interval what would your confidence level and alpha for it be?
Confidence level 99%, and alpha = 1%.
What is the difference between standard deviation and margin of error?
Standard of deviation and margin of error are related in that they are both used in statistics. Level of confidence is usually shown as the Greek letter alpha when people conducting surveys allow for a margin of error - usually set at between 90% and 99%. The Greek letter sigma is used to represent standard deviation.

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.

As standard deviation increases what happens to the sample size in order to achieve a specified level of confidence?
decreases
What combination of factors will increase the chances of rejecting the null hypothesis?
a small standard error and a large alpha level
What is the difference between standard error of sample mean and sample standard deviation?
Standard error A statistical measure of the dispersion of a set of values. The standard error provides an estimation of the extent to which the mean of a given set of scores drawn from a sample differs from the true mean score of the whole population. It should be applied only to interval-level measures. Standard deviation A measure of the dispersion of a set of data from its mean. The more spread apart the data is, the higher the deviation,is defined as follows: Standard error x sqrt(n) = Standard deviation Which means that Std Dev is bigger than Std err Also, Std Dev refers to a bigger sample, while Std err refers to a smaller sample

If you have a 99 confidence interval what would your confidence level and alpha for it be?
Confidence level 99%, and alpha = 1%.
Is apocalypse omega-level mutant?
No, she is Alpha-level.
What and who determines the alpha level in statistics?
Before conducting a significance test, the statistician will choose an alpha level. Depending upon the severity of having type I or type II error, the statistician will make the alpha level higher or lower. Generally in courts, the alpha level is .05. The other common alpha levels for significance tests are .10 and .01.
If the alpha level is increased from alpha 01 to alpha 05 what happens to the size of the critical region?
I f alpha increases the power is also increases.
