A random sample of n individuals were selected. A 95% confidence interval (\$52,000 to \$70,000) was constructed using the sample results.

Which of the following statement(s) is/are true? (Can choose answer more than 1)

If all possible samples of size n were drawn from this population, about 95% of the population means would fall in the interval (\$52,000 to \$70,000).

We do not know for sure whether the population mean is in the interval \$52,000 and \$70,000.

If all possible samples of size n were drawn from this population, 95% of the intervals established by the above method would contain the population mean.

If all possible samples of size n were drawn from this population, about 95% of the sample means would fall in the interval (\$52,000 to \$70,000).

3re Option is correct.
