Suppose we take a random sample of 50 monsters to create a 95% confidence interval for the population mean weight of all monsters. How likely is it that the sample mean weight of the random sample differs from the population mean weight of all monsters?
1) All but guaranteed; essentially a 100% confidence interval
2) There is a 95% chance that the interval contains the true mean height of all monsters
3) There is a 5% chance that the interval contains the true mean height of all monsters
4) Almost certainly no chance; essentially a 0% confidence interval
