<h2>Answer:</h2>

The statement that correctly describes the association between the variables A and B is:

Negative association.

Linear association.

<h2>Step-by-step explanation:</h2>

Clearly from the scatter plot we could see that with the increase in the value of variable A the second variable i.e. variable B is decreasing.

Hence, the association is negative association.

Also when we will draw the trend line we see that we get a parabolic path such that it best describes the point.

Hence, the association is non-linear.

A courtyard has three walls with widths

wariber [46]

Using the greatest common factor, it is found that the greatest dimensions each tile can have is of 3 feet.

---------------------------

The widths of the walls are of <u>27 feet, 18 feet and 30 feet.</u>
<u>The tiles must fit the width of each wall</u>, thus, the greatest dimension they can have is the greatest common factor of 27, 18 and 30.

To find their greatest common factor, these numbers must be factored into prime factors simultaneously, that is, only being divided by numbers of which all three are divisible, thus:

27 - 18 - 30|3

9 - 6 - 10

No numbers by which all of 9, 6 and 10 are divisible, thus, gcf(27,18,30) = 3 and the greatest dimensions each tile can have is of 3 feet.

The owner of a bakery wants to know whether customers have any preference among 5 different flavors of muffin. A sample of 200 c

Troyanec [42]

So,, there are 5 different flavors. A total of 180 people were asked. Hence, the hypothesis that there is no significant difference is that every flavor gets 180/5=36 flavors. x^2= $\sum{\frac{(x_i)^2}{m_i}}-n$ . In this case, mi is the proportion of the hypothesis, thus 36, n=180 and xi is the number of actual observations. Substituting the known quantities, we get that x^2=9. The degree of association is given by $\sqrt{X^2}/ \sqrt{N(n-1)}$ . This yields around 0.10, much higher than our limit.
