... 17. You find old research on this species of whales that only reports the z-scores of lengths and not the actual lengths of whales. One particular whale stands out to you because it has a z-score of 5.2. What does the z-score tell you? a) This whales is much larger than the mean. b) This whale is mu ...

Correlation Coefficient
... The plot that is often used when performing a residual analysis is a scatter plot of the residuals and the predicted values. A scatter plot (aka a residual plot) allows us to identify patterns in the residuals. The scatter of the residuals should be of equal magnitude across the range of the predict ...

Practice Problems
... We expect that the mean age for the US population is 44.54 years of age (although we know that this is probably incorrect). We can be 99% certain that the true population mean for age is between 43.37 and 45.71 years of age. In 99 out of 100 samples, our confidence interval would contain the true po ...

Healey`s Statistics: A Tool for Social Research Seventh
... The notation used is not standard either: the most notable (and potentially confusing) is the use of mean standard deviation but as numbers without any reference to what it means, for example 10 1.5. Without any explanation, this means nothing to someone with no knowledge of statistics and to so ...
