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.
Answer:
c. permanent damage and death
Explanation:
According to my research on the three stages of stress, I can say that based on the information provided within the question persistence of the alarm stage will ultimately result in permanent damage and death. This is because the alarm stage (also known as fight or flight) makes your heart beats faster, sending more blood to your arms and legs which if maintained long enough can cause your heart to become permanently damaged or stop.
