Answer:
3
Step-by-step explanation:

a = 3

multiply 2 and 3
2 * 3 = 6

simplify
18/6 = 3
5 liters = 5000ml
If they combine, they would have
5000 + 750 = 5750ml
one serving = 180ml
Number of serving = 5750 ÷ 180 = 31 serving with 170ml remaining
<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>
I believe in standard form this would be 31/2 + 27i/2
