Please help! this is due tmr show work too please of can!
1 answer:
The rate of change is -5/4
I find it best to use the Slope formula
M= y2-y1/x2-x1
So we to use need any 2 points on the graph (I used the first 2)
•(0,200) and (80,100)
Now we set up the problem 100-200/80-0
Then you’ll subtract and should get
-100/80
Now you’ll simplify and once you’re done simplifying your answer should be -5/4.
Here is my work. Hope this Helps!

Answer:
Alternative hypothesis: "AT LEAST ONE" of the population means is different from the others
Step-by-step explanation:
Analysis of variance (ANOVA) "is used to analyze the differences among group means in a sample".
The sum of squares "is the sum of the square of variation, where variation is defined as the spread between each individual value and the grand mean"
If we assume that we have n groups and we want to check if the population means are equal, th best way to check this it's with an ANOVA test.
The hypothesis for this case are:
Null hypothesis:
Or in words:
Null hypothesis: All treatments/samples come from populations with the same mean
Alternative hypothesis: Not all the means are equal
Or we can say:
Alternative hypothesis: "AT LEAST ONE" of the population means is different from the others
