... lengths of sheets in 2 reams are the same or different? Biological properties, on the other hand, tend to have a fairly high variability due to the many variations in genetics and environment even within a single species. How many class participant heights do you need to measure to know the average ...

... a mean of 10 hours and a standard deviation of 1.5 hours. Find the probability that the cell phone will last between 8 and 12 hours between charges. 2. Suppose that a paint manufacturer has a daily production, X that is normally distributed with a mean of 100,000 gallons and a standard deviation of ...

... family with known variance (write the Gaussian as an exponential family to remind yourself of this fact if you’ve forgotten). And of course this can be generalized: tests between two hypotheses based on likelihood ratios only depend on the data through sufficient statistics. Exercise 104: Prove this ...
