Asample has n = 7 scores with a mean of m=9. if one individual with
of x= 3 is removed from the sample, the new mean will be m=10.
a. true
b. false

the answer is. -82562234434584

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
