Question

which one/s are true?

1. a 95% degree if confidence means that the probability that true value of parameter would likely be inside the interval [a,b] is 0.95.

2. a 95% degree of confidence means that 95% out 100 interval estimates would likely contain the true value of the population parameter.

Definition Definition Method in statistics by which an observation’s uncertainty can be quantified. The main use of interval estimating is for describing a range that is made by transforming a point estimate by determining the range of values, or interval within which the population parameter is likely to fall. This range helps in measuring its precision.
