... It is straight forward to compute means, percentages, and other statistics based on the sample. The issue is: how accurate are these estimates as compared to the population parameters? Given that we don’t have population data, how are we going to assess the accuracies of estimates? If we don’t provi ...

... a standard deviation of 4 crimes per day. A random sample of 100 days was observed, and the sample mean number of crimes for the sample was calculated. Describe the sampling distribution of the sample mean. A) shape unknown with mean = 2.8 and standard deviation = 4 B) approximately normal with mean ...

... F is significantly different from 1 then the two variances are not likely to be the same. Is it possible to have a significant F -test in multiple regression and still have insignificant individual variables (that is all with t-stats less than tcrit )? Yes! It is possible to have large enough sample ...
