Answer:

The probability of observing a sample mean of x = 52 or greater from a sample size of 25 is 0.0000026

Step-by-step explanation:

Mean = $\mu = 45$

Population standard deviation = $\sigma = 6$

Sample size = n =25

Sample mean = $\bar{x} = 52$

We are supposed to find the probability of observing a sample mean of x = 52 or greater from a sample size of 25 i.e. $P(x\geq 52)$

$Z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}\\Z=\frac{52-45}{\frac{6}{\sqrt{25}}}$

Z=5.83

P(Z<52)=0.9999974

$P(Z\geq 52)=1-P(z$

Hence the probability of observing a sample mean of x = 52 or greater from a sample size of 25 is 0.0000026
