<u>Answer:</u>
<u>Null hypothesis: Policy B remains more effective than policy A.</u>
<u>Alternate hypothesis: Policy A is more effective than policy B.</u>
<u>Step-by-step explanation:</u>
Remember, a hypothesis is a usually tentative (temporary until tested) assumption about two variables– independent and the dependent variable.
We have two types of hypothesis errors:
1. A type I error occurs when the null hypothesis (H0) is wrongly rejected.
That is, rejecting the assumption that policy B remains more effective than policy A when it is <em>actually true.</em>
2. A type II error occurs when the null hypothesis H0, is not rejected when it is actually false. That is, accepting the assumption that policy B remains more effective than policy A when it is <em>actually false.</em>
They both equal 78 degrees because they are the same angle which means that they have the same degrees for f and e.
Answer:
n=0 , m= 13 A
Step-by-step explanation:
Answer:
(g ° f)(x) = 12x² + 24x + 23
(f ° g)(x) = 36x² + 72x + 49
Step-by-step explanation:
Here we go. Firstly you have to rewrite f ° g into f(g(x)), that should make it clearer. We, then substitute every x in f by g(x). So:
f(g(x)) = 4(g(x))² + 8(g(x)) + 7
= 4(3x+2)²+8(3x+2)+7
= 4(9x²+12x+4) + 24x + 16 + 17
= 36x² + 48x + 16 + 24x + 16 + 17
finally.. you need to regroup like that:
f ° g(x) = 36x² + 72x + 49
The same thing for g ° f(x)
but this time you substitute by f(x) in g(x) instead.
