It might not be a very precise estimate, since the sample size is only 5. Example: Central limit theorem; mean of a small sample. mean = (68 + 73 + 70 + 62 + 63) / 5. mean = 67.2 years. Suppose that you repeat this procedure 10 times, taking samples of five retirees, and calculating the mean of each sample.Module 2 • 2 hours to complete. In this module you learn about the models required to analyze different types of data and the difference between explanatory vs predictive modeling.

Solution: Since each throw is independent of the previous throws, we can apply the binomial distribution formula to find the probability. p = P (getting a six in a throw) = ⅙. q = P (not getting a six in a throw) = 1 – ⅙ = ⅚. According to the question, two sixes are already obtained in the previous throws.Begin using the common terminology of statistics by talking about the data using basic metrics and descriptors of the set.
