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.
In this question, we're trying to find how much a sale clerk earns from a sale.
We know that the DVD player costs $250
We also know that the TV costs $600
The sales clerk has a 19% commission rate, this is the money that they make from the sale.
To find the money the sales clerk got from the sale, we have to add the total spending and multiply it by 0.19
250 + 600 = 850
850 · 0.19 = 161.5
This means that the sales clerk made $161.50 in commission from the sale.
Answer:
$161.50
