Answer:
1) 70 for both of them
2) Plot A's range is 100-50 = 50, Plot B's range is 100 - 40 = 60 so Plot A has the lesser range
3) Plot B's IQR is 85 - 60 = 25, Plot A's IQR is 80 - 65 = 15 so Plot B has the greater IQR
4) A: 80, B: 85
5) A: 65, B: 60
6) 50
7) 100
8) Plot B, see #2 for work
9) 50% - 50% of data is always between Q1 and Q3
10) 25%
11) 25%
Answer:
C.) The relationship is proportional
Step-by-step explanation:
If D is true, then it is not proportional, constants of proportionality must not include multuplting or subtracting from anything.
Also quick way to tell— the line doesn’t start from 0,0
Answer:
a. the line that passes through the most data points.
Step-by-step explanation:
Regression analysis, is used to draw the line of‘ best fit’ through co-ordinates on a graph. The techniques used enable a mathematical equation of the straight line form y=mx+c to be deduced for a given set of co-ordinate values, the line being such that the sum of the deviations of the co-ordinate values from the line is a minimum, i.e.
The least-squares regression lines is the line of best fit
Answer:
The mass of an object is directly proportional to its inertia.

Where
m = mass
I = inertia
Step-by-step explanation:
We can first of all start by defining the two key terms present here - mass and inertia.
The mass of an object is the quantity of matter contained in the object.
The inertia of an object is the resistance of an object which is in a state of rest to motion
The mass of an object is directly proportional to its inertia.
The heavier an object is, the more inertia it has. To put things into perspective, you can easily push a bicycle because it does not really have a lot of mass, as opposed to pushing an eighteen-wheeler trailer.
Answer: Our required probability is 0.515.
Step-by-step explanation:
Since we have given that
Probability that the respondents voted in favor of Scot Walker P(F) = 56%
Probability that the respondent voted in not favor of Scot Walker = 100-56 = P(F')=44%
Probability of those who did vote in favor had a college degree = 36% = P(C|F)
Probability of those who did vote against had a college degree = 44% = P(C|F')
So, we will use "Conditional Probability":
probability that he voted in favor of Scott Walker given that they had a college degree is given by

Hence, our required probability is 0.515.
