Answer:
One of the assumptions we sometimes need to make when performing statistical inferences is that the response variable in the population has a Normal distribution. Is it possible to check that this assumption is satisfied?
Statement A is correct
Step-by-step explanation:
When performing statistical inferences, one of the assumptions often made is that the response variable in the population has a normal distribution.
Since we do not have the whole population, the above assumption cannot put to a check.
However, the t distribution is robust to modest departures from normality, thus it can be used, if there are no major outliers in the plot of the data.
Therefore, statement A is correct.
