A researcher measures the relationship between the number of interruptions during a class and time spent "on task" (in minutes). Answer the following questions based on the results provided. Number of Interruptions Time Spent
9 16
3 40
7 19
2 32

Required:
a. Compute the Pearson correlation coefficient.
b. Multiply each measurement of interruptions times 3 and recalculate the correlation coefficient.

answer: median

step-by-step explanation:

the median is the middle value when a data set is ordered from least to greatest

add them

step-by-step explanation:

idk you did not give the options or numbers so you cant solve it

option a is correct.

only one solution to the system of equations

step-by-step explanation:

if the graph of the equations do not intersects(i.,e if they are parallel) then, there are no solutions that are true for both the equations.

if the graph of the equations intersects, then there is one solution and that is true for both the equations.

since, in the given figure:

the two lines intersect each other

⇒there is only one solution which satisfy both the lines of an equations.

therefore, there is only one solution to the system of equation
