True
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.
Sample size and confidence level width are inversely related. As the sample size increases, the width of the confidence interval decreases, resulting in a more precise estimate of the population parameter. Conversely, a smaller sample size leads to a wider confidence interval, reflecting greater uncertainty about the estimate. This relationship emphasizes the importance of an adequate sample size in achieving reliable statistical conclusions.
yes
8mm is a little wider.
The confidence interval becomes wider.
No, it is not. A 99% confidence interval would be wider. Best regards, NS
That, my friend, is not a question.
no
It will make it wider.
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.

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.
a straight is narrow body of water, and a channel is a wider body of water.
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.
The opposed of narrow is wide.
