To determine what the math problem is, you will need to look at the given information and figure out what is being asked. Ordering a data set from lowest to highest value, you take samples of size n = 16. (population mean) (population standard deviation) n (sample size) The most commonly used confidence levels are 90%, 95%, and 99% which each have their own corresponding z-scores (which can be found using an equation or widely available tables like the one provided below) based on the chosen confidence level. Since any linear combination of normal variables is also normal, the sample mean \(\bar X\) is also normally distributed (assuming that each \(X_i\) is normally distributed). Unfortunately, unless the full population is sampled, the estimate p most likely won't equal the true value p, since p suffers from sampling noise, i.e. Even-numbered questions are all in a negative .
