... Mode: The mode of a sample is the most frequent value. In the sample above, the mode is non-unique - both 2 and 5 occur twice. It may not exist at all if no two values occur more than once. We can usually make a sample with at least one mode by grouping the samples into bins of almost-identical valu ...

... smaller, but it doesn’t change anything – the mean is still significantly different from 19 (but not 18). 3) a) Find z .0005 . Make a diagram! The diagram for z will be a Normal curve centered at zero and will show one point, z .0005 , which has 0.05% above it (and 99.95% below it!) and is above zer ...

Suppose the difference between self-reported and actual amounts of smoking is on average equal to 0, normally distributed, and unrelated to the actual price youths pay for cigaret ...
