Answer:

Option: A is the correct answer.

A. Perfect negative association.

Step-by-step explanation:

A perfect association in a scatter plot is one in which we get a line of best fit such that all the points could lie on that line or we can say that the points have a linear association.

Also a negative association is one in which there is a  increase in one variable  while decrease in the other.

So, here in the scatter plot we could clearly observe that with the increase in the Variable X the other variable i.e. Variable Y is decreasing.

Hence, Option: A is the correct answer.

A. perfect negative association

6) The amount of Jen's monthly phone bill is normally distributed with a mean of $70 and a standard
alexandr402 [8]

Answer:

i)The correct option is  D.) 99.74%

ii) The correct option is B.) 68.26%

Step-by-step explanation:

i) P(10≤X≤70) = P(  (10−40)/10  ≤Z≤   (70−40 )/10 ) =  Pr(−3≤Z≤3)

= 0.9987 - 0.0013 = 0.99734

Therefore the percentage of Jen's monthly phone bills are between $40 and $100 is D.) 99.74%

ii)P(2.1≤X≤3.1) = P(  (2.1 − 2.6) /0.5   ≤ Z  ≤ (3.1−2.6 )/0.5)  =  Pr(−1  ≤Z  ≤1) )

=  0.8413 − 0.1587  =  0.6826

Therefore the percentage of students at college have a GPA between 2.1 a,d 3.1 is B.) 68.26%
