Hi Brand,
Investopedia gave this nice example for CI
Assume the interval (height of BB plyers) is between 72 inches and 76 inches (mean 74). If the researchers take 100 random samples from the population of high school basketball players as a whole, the mean should fall between 72 and 76 inches in 95 of those samples.
What the values of 0.3335 and 0.9376 represent I don't know, but I do know they are points either side of the mean on a bell shaped distribution curve - the values that fall in this range represent 95% of the sample.
