Hi,
To a single Bernoulli Trial (one car leaving the park goes left or
right)if I "preview" go to right and this happens trial out is success
.But what p probability I can give to this? I imagine the correct way
is tally the frequencies at ,eg, 10 cars go right and then do my "only
trial", with so
The formula wich gives the Standard Deviation ,
SD=((x-mean)^2/(n-1))^0.5 ,can be applied to Any data set. When we
have that value we know two things about the set: The Mean and the SD.
With this two values We can have one powerful intuitive use to them:
The "centre" of the set is the mean and 68
