Answer: sample size
Explanation: sample size simply means the number of observations or items chosen as a representation of a population. Sample size is an important terminology used in statistical analysis as most statistical or experimental research cannot be performed using all the available observations in the entire population either due to cost or total impossibility. The larger the sample size, the better the generalization made about the entire population.
Therefore, a sample size consisting of 10,000 participants or observations will generalize more and hence, attract greater value and interest than the same analysis with a sample size of 24 participants.

Explanation:
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.
