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:
The correct answer would be Verbal Communication.
Explanation:
When someone is able to convey his message to the other person or group of persons, in a strong manner, with clear and unambiguous delivery of message, the person is said to have extra ordinary communication skills. There are different types of communications, like verbal, writing, gestures, facial, body, etc. The best way to communicate through the other person is through mouth.
