Answer:
d. Statistical Inference learning
Explanation:
Statistical inference is the process of utilizing data analytics to find the properties of the hidden probability distribution. Inferential statistical analysis studies the properties of a population, for instance by testing the hypotheses and finding estimates for estimates.
Therefore the answer to the above question is statistical learning for learning to predict who has higher chance to survive on Titanic.
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.
