$P(\bar X\:$ or $P(\bar X\:$

Step-by-step explanation:

Calculate the z-score of 51.5 using the formula:

$z=\frac{\bar X-\mu}{\frac{\sigma}{\sqrt{n} } }$

We substitute $\bar X=51.5,n=36,\sigma=5, \mu=50$

$\implies z=\frac{51.5-50}{\frac{5}{\sqrt{36} } }$

$\implies z=\frac{1.5}{\frac{5}{6} }=1.80$

From the standard normal distribution table, the area to the left of 1.80 is 0.9641

Therefore $P(\bar X\:$
