In the construction of confidence interval if all other quantities are unchanged an increase in the sample size will lead to a wider interval is this statement is true or false?
True
Is it true that the wider the confidence interval the less precise is the estimate?
All things being equal, a wider confidence interval (CI) implies a higher confidence. The higher confidence you want, the wider the CI gets. The lower confidence you want, the narrower the CI gets The point estimate will be the same, just the margin of error value changes based on the confidence you want. The formula for the CI is your point estimate +/- E or margin of error. The "E" formula contains a value for the confidence and the higher the confidence, the larger the value hence the wider the spread. In talking about the width of the CI, it is not correct to say more or less precise. You would state something like I am 95% confident that the CI contains the true value of the mean.
Is it true that the wider the interval in grouping scores the more information is lost?
yes
Which is wider 8mm or 516 in?
8mm is a little wider.
What part of the equation makes the graph narrow or wide?
its not the equation that matters it is how you map it out on the graph, the vertical and horizontal axis are interchangeable. For example if x is the vertical axis and y is the horizontal axis the graph would look different than if y was the vertical axis and x was the horizontal axis. The narrow and wide of a graph depend on the horizontal axis ( how quickly the numbers increase and or how far apart the markers are spaced) ...If the intervals are counted by 5 the graph would be wider than if the intervals were counted by 500.
What happens to the confidence interval if you increase the confidence level?
The confidence interval becomes wider.
Is a 95 percent confidence interval for a mean wider than a 99 percent confidence interval?
No, it is not. A 99% confidence interval would be wider. Best regards, NS
When the confidence interval is wider than a prediction interval?
That, my friend, is not a question.
Is it true that the larger the standard deviation the wider the confidence interval?
no
What effect increasing only the population standard deviation will have on the width of the confidence interval?
It will make it wider.
What happens to the confidence interval as the standard deviation of a distribution increases?
The standard deviation is used in the numerator of the margin of error calculation. As the standard deviation increases, the margin of error increases; therefore the confidence interval width increases. So, the confidence interval gets wider.
In the construction of confidence interval if all other quantities are unchanged an increase in the sample size will lead to a wider interval is this statement is true or false?
True
What is the difference between a firth and a bay?
The difference is a bay is rounder and not so narrow. a firth is long and narrow and a bay is round and wider.

What is the difference between a wide blade and a narrow blade hoof knife?
I dont know the answer to this question so go and read books and get smart. i think the wider blade is wider and the narrow blade is narrower.
What is the difference between strait and the a channel?
a straight is narrow body of water, and a channel is a wider body of water.
Will The finite population correction factor lead to a wider confidence interval?
No since it is used to reduce the variance of an estimate in the case that the population is finite and we use a simple random sample.
