Suppose X is a random variable with
X - N(90, 52)
and let
u = the mean of X
me = the median of X
mo = the mode of X
Transcribed Image Text:Suppose X is a random variable with X - N(90, 52) and let u = the mean of X me = the median of X mo = the mode of X
Let
X = sample mean of size n
when we draw a random sample from the population specified above. According to the sampling distribution of X we know that:
True False
If you increasen, the observed sample mean, a, will always get closer to u = 90.
always has a normal distribution.
The mean of X is u
90.
The standard deviation of X iso = 5.
