A population of values has a normal distribution with
\(\displaystyle\mu={239.5}\)
and
\(\displaystyle\sigma={32.7}\)
. You intend to draw a random sample of size
\(\displaystyle{n}={139}\)
.
Find the probability that a single randomly selected value is greater than 235.9.
\(\displaystyle{P}{\left({X}{>}{235.9}\right)}=\)
?
Write your answers as numbers accurate to 4 decimal places.
