If you have a 99 confidence interval what would your confidence level and alpha for it be?
Confidence level 99%, and alpha = 1%.
What happens to the width of the confidence interval if you decrease the confidence level?
The width reduces.
What is the confidence interval for 85 percent?
it would be with a level of significance of 0.15.
What would happen to the width of the confidence interval if the level of confidence is lowered from 95 percent to 90 percent?
decrease
What confidence level has become the most used or traditional confidence level among business researchers?
95% confidence level is most popular
The width of a confidence interval is equal to twice the value of the margin of error?
No. The width of the confidence interval depends on the confidence level. The width of the confidence interval increases as the degree of confidence demanded from the statistical test increases.
What happens to interval when level of confidence is increased?
it increases
What happens to the confidence interval if you increase the confidence level?
The confidence interval becomes wider.
What is confidence associated with an interval estimate is called the?
confidence level
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 most controllable method of increasing the precision of or narrowing the confidence interval?
Confidence intervals represent an interval that is likely, at some confidence level, to contain the true population parameter of interest. Confidence interval is always qualified by a particular confidence level, expressed as a percentage. The end points of the confidence interval can also be referred to as confidence limits.
True or False The higher the confidence level the narrower the confidence interval?
True.
What happens to the width of the confidence interval if you decrease the confidence level?
The width reduces.
What Happens To The Width Of The Confidence Interval If You Decrease The Confidence Level Decrease The Sample Size or Decrease the margin of error?
The width of the confidence interval willdecrease if you decrease the confidence level,increase if you decrease the sample sizeincrease if you decrease the margin of error.
What is the confidence interval for 85 percent?
it would be with a level of significance of 0.15.
What is Confidence Intervals of Degree of Confidence?
, the desired probabilistic level at which the obtained interval will contain the population parameter.
Why does margin of error increases while level of confidence increases?
The margin of error increases as the level of confidence increases because the larger the expected proportion of intervals that will contain the parameter, the larger the margin of error.
