For Sherlock Holmes the "science of deduction" was the ultimate key to solving every mystery. Distance between footprints (length of stride) told the master detective the height of a criminal he was pursuing. What kind of relation is there between a person's height and the length of stride? A random sample of 12 people provided the following data. For this data x= length of stride in inches and y= person's height in inches. Suppose we wanted to test for a significant correlation at the .05 level of significance.

x	15	17	19	11	16	22	17	25	14	15	25	26
y	66	67	76	59	72	78	75	87	64	68	81	87
