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.
Step-by-step explanation:
If the library surveyed 240 people and only 15% chose documentaries, then only 36 people chose documentaries and the other 204 chose something else other than documentaries. You had to get 15% into decimal form and to do that you move the "." in 15.0% left 2 places so you get 0.15. Then you multiply 240 by 0.15 and you get 36.
True or False question, I would say that it's true.
Answer:
(2/3)y - (8/3) = x For the first one maybe?
Step-by-step explanation:
1. y = (3/2) x + 4
y - 4 = (3/2) x
(2/3)y - (8/3) = x
2. If output is 2, f(x) = 2.
So, 2 = (3/2) x + 4
-2 = (3/2) x
-4 = 3x
x = -3/4
