95% confidence interval for rate can be expressed as : Rate +/- 1.96 Rate/sqrt(n) where n is the number of events and sqrt means square root. Hope this helps. Omar.
The answer will depend on whether the confidence interval is one-sided, or two-sided and, if two-sided, whether or not it is symmetrical. Symmetrical 2-sided: ±0.189
A term used in inferential statistics which measures the probability that a population parameter will fall between two set values. The confidence can take any number of probabilities, with most common probabilities being : 95% or 99%.
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 if you repeated your experiment then, for the stated percentage of cases, the statistic would lie within the CI.
The interval between two occurences is TIME.
The answer will depend on whether the interval is one-sided or two-sided; and if two-sided, whether it is symmetrical.For a symmetrical two-sided confidence interval, the Z value is 0.974114The answer will depend on whether the interval is one-sided or two-sided; and if two-sided, whether it is symmetrical.For a symmetrical two-sided confidence interval, the Z value is 0.974114The answer will depend on whether the interval is one-sided or two-sided; and if two-sided, whether it is symmetrical.For a symmetrical two-sided confidence interval, the Z value is 0.974114The answer will depend on whether the interval is one-sided or two-sided; and if two-sided, whether it is symmetrical.For a symmetrical two-sided confidence interval, the Z value is 0.974114
For a two-tailed interval, they are -1.645 to 1.645
The answer depends on whether the confidence interval is one sided or two sided.
The two tailed critical value is ±1.55
2.326 (one sided) or 2.578 (two sided)
The answer will depend on whether the interval in one or two sided. One-sided: Z < 1.28 or Z > -1.28 Two-sided: -1.64 < Z < 1.64
It depends on whether the interval is one sided or two sided. The critical value for a 2-sided interval is 1.75
95% confidence interval for rate can be expressed as : Rate +/- 1.96 Rate/sqrt(n) where n is the number of events and sqrt means square root. Hope this helps. Omar.
A confidence interval, for a given probability, is the interval within which the true value may be found with that probability if the null hypothesis is true. There are two possible reasons why a confidence interval may be asymmetrical. One is that the alternative hypothesis is asymmetrical: for example, H0 is X = 5 and H1 is X > 5 (rather than X ≠5). The other possible reason is that the test statistic has an asymmetrical distribution. Either of these can give rise to asymmetrical CIs.
The answer depends on whether the interval is one-sided or two-sided and, if two-sided, whether or not it is symmetrical.
The answer depends on whether the test is one-tailed or two-tailed.One-tailed: z = 1.28 Two-tailed: z = 1.64
The answer will depend on whether the confidence interval is one-sided, or two-sided and, if two-sided, whether or not it is symmetrical. Symmetrical 2-sided: ±0.189
