Considering the situation described, the scientist's null and alternative hypothesis are described by:
Null hypothesis 
; Alternative hypothesis 
.
<h3>What are the hypothesis tested?</h3>
At the null hypothesis, it is tested if there is no difference, that is, the difference of the means represented by 
is of 0, hence:
At the alternative hypothesis, it is tested if there is a difference, hence:

Think of it as a normal linear equation first. Let's find the slope.
m = rise/run = (3-1)/(0-1) = -2
We know the slope is negative now, so we can immediately get rid of the first two answers. Now, we know that the solutions must be under the line itself, so we can try figuring it out by testing some points. Let's use (0,0).
Is 0 </> 0+3? Since it's <, then we know the last answer is correct (y < -2x + 3).
Answer:
Twelve-fifths
Step-by-step explanation:
Tan θ = opposite ÷ adjacent
Tan A =24/10
=12/5
How long would it take $120/hr to add up to $1000?
Divide $1000 by $120/hr:
$1000
----------- = 8 1/3 hours, or 8 hours 20 minutes.
$120/hr
