Table 2.32 gives the times for five races in which two joggers participated.

Table 2.32

Jogger A.........................Jogger B
44 .......................................48
45........................................49
43.......................................38
48.......................................40
45.......................................50

(a) Use technology to construct a scatterplot of the race times.
(b) Use technology to find the correlation.
(c) A sixth race is held on a very windy day, and jogger A takes 50 minutes while jogger B takes a whole hour to complete the race. Recalculate the correlation with this point added.

(d) Compare correlations from parts (b) and (c). Did adding the results from the windy day have an effect on the relationship between the two joggers?
