# What happens to the confidence interval if you increase the confidence level?

The confidence interval becomes wider.

### 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 will decrease if you decrease the confidence level, increase if you decrease the sample size increase if you decrease the margin of error.

### What happens to the width of the confidence interval if you decrease the confidence level?

The width reduces.

### 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.

### If you have a 99 confidence interval what would your confidence level and alpha for it be?

Confidence level 99%, and alpha = 1%.

### 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 is meant by a 95 percent confidence interval?

Confidence Intervals Confidence interval (CI) is a parameter with a degree of confidence. Thus, 95 % CI means parameter with 95 % of confidence level. The most commonly used is 95 % confidence interval. Confidence intervals for means and proportions are calculated as follows: point estimate ± margin of error.

### What is Confidence Intervals of Degree of Confidence?

, the desired probabilistic level at which the obtained interval will contain the population parameter.

### What is the confidence interval for 85 percent?

it would be with a level of significance of 0.15.

### What is the Z score for a confidence level of 0.01?

The answer depends on whether the confidence interval is one sided or two sided.

### Why does the margin of error increase as the confidence increases?

The margin of error is dependent on the confidence interval. I'll give you examples to understand it better. We know: Confidence Interval (CI) = x(bar) ± margin of error (MOE) MOE = (z confidence)(sigma sub x bar, aka standard error of mean) When CI = 95%, MOE = (1.96)(sigma sub x bar) When CI = 90%, MOE = (1.64)(sigma sub x bar) Naturally, the margin of error will decrease as confidence level decreases.

### What z value corresponds to a confidnece level of 86?

The value for a one-sided confidence interval of 86% is 1.08

### What is the critical z value that corresponds to a confidence level of 92 percent?

It depends on whether the interval is one sided or two sided. The critical value for a 2-sided interval is 1.75

### What are the advantages of a small confidence interval in statistics?

The smaller the confidence interval, the more certain you are of the answers. Remember confidence level and confidence interval (margin of error) are 2 separate things. So if you are using an industry standard confidence level of 95% and 5% margin of error in a standard statistical table, then you could say, for example, with 95% certainty that 60% of those polled would vote for John McCain. Another way of saying this is even though… Read More

### What is the critical z value that corresponds to a confidence level of 88 percent?

z = 1.56 gives a 2-tailed interval for 88%. z = 1.56 gives a 2-tailed interval for 88%. z = 1.56 gives a 2-tailed interval for 88%. z = 1.56 gives a 2-tailed interval for 88%.

### What Z value corresponds to a confidence level of 98 percent?

The answer depends on whether the interval is one-sided or two-sided and, if two-sided, whether or not it is symmetrical.

increase our productivity increase our confidence level employers and others members may respect us doing work with calm and no rushing

### What confidence level has become the most used or traditional confidence level among business researchers?

95% confidence level is most popular

### 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… Read More

### What is a confidence interval in statistics?

When you calculate a statistic the result is not going to be perfectly accurate because of random errors in your observations. You therefore can give the result as one value along with a confidence interval (CI) around it. There are two interpretations of a CI. One interpretation is that you can be confident, with the stated level of confidence, that the true value of your statistic lies within the CI. The other interpretation is that… Read More

### Can more types of calculations be performed at a nominal level than an interval level?

No. The interval level is more refined and so enables calculations which are not available at the nominal level.

### How should I construct a confidence interval for the population proportion p with n equals 144 and x equals 82 with a 90 percent confidence level?

The confidence interval will be Pi+-z*sp z5%= 1.6449 Pi = x/n Sp = Sqrt(Pi(1-Pi)/n) Pi ~= 0.5694 Sp = Sqrt(.5694*0.4306/144) ~= 0.0413 Pi - 0.0679 < p < Pi + 0.0679 0.5016 < p < 0.6373 You can do this on your TI-83/84 with 1-PropZInt (Stat->Tests->A)

### What does CL mean in mathematical terms?

It may stand for the number 150 (Roman numbers). In statistics, CL usually refers to "Confidence Level," which establishes a likelihood (typically 90 or 95%) an estimated value will fall within a given Confidence Interval (a range of estimated values).

### What is the relationship between confidence interval and standard deviation?

Short answer, complex. I presume you're in a basic stats class so your dealing with something like a normal distribution however (or something else very standard). You can think of it this way... A confidence interval re-scales margin of likely error into a range. This allows you to say something along the lines, "I can say with 95% confidence that the mean/variance/whatever lies within whatever and whatever" because you're taking into account the likely error… Read More
