To say that +/- 4.2 is a 95% confidence interval for the population mean. μ. is to say that, in repeated samples, 95% of these intervals capture . μ. Conclusion: Our sample of 50 freshmen gave = 112. The resulting 95% confidence interval is 112 +/- 4.2 which can be written as (107.8, 116.2).

and the resulting 95% confidence interval is. 47. C The only correct statement is the first one --The large-sample confidence interval formula for proportions is valid if np ≥ 15 and n(1-p) ≥ 15. The large sample confidence interval only contain the true value a certain percentage of the time. A 95% CI will contain the value 95% of the time.

If we were going to construct a confidence interval at a 95 percent confidence level for a sample of 26 observations, we would have 25 degrees of freedom. The value of t is not the 1.96 of a normal distribution. It is 2.060, found by looking for the intersection of the 25 degrees of freedom row and the 95% confidence level column.
