What is the answer to the whole of this question? ¿

a) The point (140, 57) lies furthest from the rest of the data, therefore making it an outlier.

b) Since the points are all going in somewhat of a positive diagonal direction, there is a positive correlation.

c) We can estimate that the new student weighs approximately 155 kg.

1. (140,52)

2. Negative Correlation

3. about 150cm

Step-by-step explanation:

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
