Emily wants to determine the relationship between the number of people in a household (x) and the last 4 digits of their phone number (y). She randomly selects 100 households in her town and examines the data. What is the best estimate of the correlation coefficient between x and y? A. -0.5 B. 0 C. 0.5 D. 1

0.5

Step-by-step explanation:

there may be some relationship

there can't be a negative probability

probably not 0, there could be something

probably not a complete correlation of 1

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
