... Say you want to test with 98% confidence that the standard deviation of the weights of cats is no more than three ounces. If you want to test this claim with a confidence interval, how much area would be under the curve between the lower and the upper bounds of the confidence interval? After constru ...

... • Argue that to sample from fa, one can do a two stage sampling. Stage 1, determine the state, f or δa by sampling uniformly from [0, 1]. If the sample is in [0, 1 − ] then the state is f , otherwise it is δa . Next, sample from the appropriate distribution. • Write a computer program to sample fr ...

... 1. To determine President Obama’s re-election chances, I decide to telephone all my friends and ask whether they plan to vote for him. What kind of sampling is this? 2. What method of data collection would best be used to determine whether large doses of vitamin C help to prevent catching a cold ? 3 ...

Overview for Confidence Intervals and Hypothesis
... 1. Confidence Interval Method (uses a confidence interval to measure strength of evidence) This method uses a confidence interval to create a feasible region for the unknown parameter using sample data. If the confidence interval contains the hypothesized value then this would support a conclusion t ...

... We then compare this value to a critical value from the F-distribution table. Since this is a two tail test with alpha = .10, we use the table with 0.05 in the upper-tail of the F-distribution. Two sets of degrees of freedom are used with the F-distribution. Across the top of the F-table we look for ...
