Answer:
c. We have evidence that there is a difference in population median employee satisfaction rating before and after the commission change.
Step-by-step explanation:
Pvalue is less than the alpha-level:
If the pvalue is less than the alpha-level, we have that there is sufficient evidence of the hypothesis for the population mean/median/standard deviation we are testing.
In this question:
Pvalue less than the alpha-level, so there is evidence that there is a difference in the population median. This means that the correct answer is given by option C.
Answer:
$52 to $45
Step-by-step explanation:
First put their income into a ratio:
520 to 450
Now you can put it into a fraction and then simplify it:
520/450
Divide each by 10
520/10 = 52
450/10 = 45
So 52/45
.2 is the decimal representation of 2/10
