9. A study Iooked at several attributes on participants. The table below gives some measurements from participanl for Resting Blood pressure and Maximum Heart Rate. | Max Heart rate 168 143 144 m 114 142 140 187 112 150 | Resting up 105 155 110 120 150 140 120 130 130 145 the scatterplotfmmthefull datasetisbelow.

IIllin'oulrl you classy this correlation as strong. moderate or weak? a] Predict Resting BF. when Max Heart Rate Is 100, and when It is 1616. Explain why each prediction is valid or not. Using the data In the table above. calcuiate the residuai when Max Heart Rate is 140. f} g] If the Max Heart Rate Increases by15, what isthe predicted change In the Resting BF? Be sure to note whether this is an Increase or decrease
