MATH 103 Review Sheet Test #3
... Calculations: Compute the percent in a sample and the associated margin of error [use m = z/2n_]. Use these two numbers to construct a confidence interval for the true percentage for the entire population. (pp. 23 & 24, 28) Compute the sample size needed to achieve a certain margin of error and the ...

The Central Limit Theorem: A Group Activity to Die For!
... Recall the premise of the Central Limit Theorem: The mean of a random sample will approximately follow a normal distribution with mean ! and standard error ! , regardless of n the distribution of the population. The theory requires a sample size of at least 30 if the population distribution is unkno ...
