Answer:
Mean of sampling distribution=3.5
Standard error of sampling distribution=0.219
Explanation:
We know that
The average of catching fish per fishing trip=μ=3.5
and
The standard deviation of catching fish per fishing trip= σ=1.2.
We have to find the mean and standard error of sampling distribution of 30 fishing trips i.e. μxbar=? and σxbar=?
Mean of sampling distribution=μxbar=μ=3.5
Standard error of sampling distribution=σxbar=σ/√n
Standard error of sampling distribution=σxbar=1.2/√30
Standard error of sampling distribution=σxbar=1.2/5.4772
Standard error of sampling distribution=σxbar=0.219
Thus, the mean and standard error for a sampling distribution of 30 fishing trips are 3.5 and 0.219.

In this scene from <u>Hamlet Act V</u>, the skulls are a symbolism; they represent the death (end of life on earth). They contribute to Hamlet’s understanding of death because, as he sees the <u>anonymous skulls</u>, he begins to realize that nothing accomplished in life matters in the face of death, as we are all equal in death.
This is an example of spontaneous recovery.
There was no reason for Mia to stop sleeping when the light was turned off, but it happened. Similarly, even though there was no reason for her to manage to sleep with the lights off again, it happened as well. It was spontaneous, meaning that she didn't have to learn it all over again - it just happened.
