Question

In estimation,
data from the population is used to estimate the population parameters
the mean of the population equals to the mean of the sample

known.
O Its mean is also its mode.
O It is bell shaped and symmetrical.
As the number of degrees of freedom increases, the t distribution approaches the standard normal
distribution.
It has more area in the tails and less in the center than does the standard normal distribution.
