WebInterpretation of a Confidence Interval. In most general terms, for a 95% CI, we say “we are 95% confident that the true population parameter is between the lower and upper calculated values”. A 95% CI for a population parameter DOES NOT mean that the interval has a probability of 0.95 that the true value of the parameter falls in the interval. WebAs shown in Figure 2, the "t distribution" calculator can be used to find that 0.086 of the area of a t distribution is more than 1.96 standard deviations from the mean, so the probability that M would be less than 1.96s M from μ is 1 - 0.086 = 0.914.

If the confidence level ( CL) is 95%, then we say that, "We estimate with 95% confidence that the true value of the population mean is between 4.5 and 9.5." Exercise 7.2.1. Suppose we have data from a sample.

WebSolution: Once again, the sample size was 10, so we go to the t-table and use the row with 10 minus 1 degrees of freedom (so 9 degrees of freedom). But now you want a 90% confidence interval, so you would use the column with a two-tailed probability of 0.10. Looking down to the row for 9 degrees of freedom, you get a t-value of 1.833.
