A correlation coefficient is always a value in between -1 and 1
The closest a coefficient to -1, the correlation is a strong negative correlation
The closest a coefficient to 1, the correlation is a strong positive correlation
The closest a coefficient to 0, there is no correlation at all
The coefficient -0.61 shows a strong negative correlation
This means that the relationship between the age and the violation is an inverse relationship; as age increases, violation decreases
Answer: option C
Answer: 37
Step-by-step explanation:
Given : Significance level :
Critical value :
margin of error : E= 1 mile per gallon
Population standard deviation: miles per gallon.
We know that when the population standard deviation is known then the formula to find the sample size is given by :
[Round to the next whole number.]
Hence, the required number of automobiles should be used in the test = 37
Has to be B other I don't know
Answer:
The sample space is:
Step-by-step explanation:
The sample space of an experiment is a set of all the possible values that satisfies that experiment.
The five supervisors are A, B, C, D and E.
Two are to selected.
The number of ways to select 2 supervisors from 5 is:
The sample space will consist of 10 combinations.
The sample space is:
Answer: $15.00 per person.

Explanation:
______________________________
Given that there are "4 people" (that is, "Kianna and three friends");
____________________________________________________
and a total of "$58.49" ; to be divided equally among 4 (four) people;
______________________________
we are asked to <em><u>estimate</u></em> the amount that EACH person will pay.
______________________________
For an <em><u>ESTIMATE</u></em>, $58.49 is ABOUT $60.00; or "60 dollars". ;
and (60 dollars) / 4 = 15 dollars {$15; or $15.00}.
60/4 = 15; or 60/4 = (60÷2)/(4÷2) = 30/2 = 15.
