a point estimate
Give this one a try later!
a single numerical value, a "best guess" of a population parameter, based
on the data in a random sample
The standard deviation(CLT)
, Give this one a try later!
equal to the population standard deviation divided by the square root of
the sample size
A one-tailed alternative is
Give this one a try later!
one that is supported only by evidence in a single direction.
sampling error(estimation error)
Give this one a try later!
the difference between the pint estimate and the true value of the
population parameter being estimated
Central Limit Theorem
Give this one a try later!
The theory that, as sample size increases, the distribution of sample means
of size n, randomly selected, approaches a normal distribution.
If the p-value is small, less than 0.05
