More Central Limit Theorem    Suppose we roll a fair D6 100 times, and let be the average of the rolls. Estimate .  Let be each roll's result. Then we have previously calculated . We have: So, by the CLT, . Even though takes on decimal values, it's still a discrete random variable. The sum of the rolls can only take on integer values, so will take on the values . Last time, we described the continuity correction as \"extending the range by half a unit's width in each direction\". Here, the width of one unit is . So:       Confidence Intervals  Idea: suppose we collected (i.i.d.) measurements which have some population mean and variance . We calculate the average: and we want to estimate the value of from the collected data. Previously, we've discussed the MLE, the single most likely estimate of the parameter. Now, we'd like to give a range where we can say something like: \"we are 95% confident that .\"  From the CLT, if is large enough, we approximate . We can think of an interval centered at as a collection of numbers within a certain distance of . We'd like to choose a distance so that our measured is within of . We can shift our point of view here: if is within of , then is within of .  TODO: image  To pick the distance , we want to make our interval large enough so that there's only a small amount of area under the normal curve outside of the interval. So:   Pick some value (representing the area under the curve outside the interval)    Let (this is the standardized -score of the right-hand side of the interval)    Then, the interval will be:      For , we'll have . So:    The 95% confidence limits are given by:       The term is called the standard error of the mean . (It's the standard deviation of .)    We don't know the true value of , just like we don't know the true value of . So we'll have to use our sample of measurements to estimate , and then use that estimate to give us our range of values for .    Let be (i.i.d.) measurements. Then the sample mean is: and the sample variance is:     Why here? It turns out that, as defined above, is an unbiased estimator for , whereas it wouldn't be if we divided by instead. (We'll ommit both the calculation justifying this and a more conceptual explanation for now.)  So, we can adjust the confidence limits from the theorem:     Suppose we're given measurements below.                            We're just practicing the computation here, so we'll pretend that 5 measurements is large enough for the CLT to apply.     This way of computing confidence limits only applies if we can think of the parameter we're estimating as a mean.    Suppose we flip a coin 100 times and see 40 heads. Find a 98% confidence interval for the bias .  Let indicate heads on each flip. Let and . Then: So a 98% confidence interval for is also a 98% confidence interval for .  In this setting, we can simplify the computation of and , using our knowledge of the binomial distribution . So and . We don't know the value of , so we'll use the MLE . So:   For a 98% confidence interval, we have , so: Then, the confidence limits are: For comparison, the 95% confidence limits are:      "
