Chapter 6: Monte Carlo Methods for Inferential Statistics
... Methods in inferential statistics are used to draw conclusions about a population and to measure the reliability of these conclusions using information obtained from a random sample. Inferential statistics involves techniques such as estimating population parameters using point estimates, calculatin ...

... • Suppose that I want to conduct a survey and want to estimate p = proportion of voters who favour a downtown location for a casino: I know that the approximate value of p is • p* = 0.50. This is also a good choice for p if one has no preliminary estimate of its value. • I want the survey to estimat ...

Comparing Two Population Means (matched
... Twenty-four males age 25-29 were selected from the Framingham Heart Study. Twelve were smokers and 12 were nonsmokers. The subjects were paired, with one being a smoker and the other a nonsmoker. Otherwise, each pair was similar with regard to age and physical characteristics. Systolic blood pressur ...
