Pоlice crime scene investigаtоrs sоmetimes meаsure footprints аt crime scenes so that they can learn something about criminals. Listed below are foot lengths (mm) and heights (mm) of males. Is there sufficient evidence to conclude that there is a linear correlation between foot lengths and heights of males? Results Table Foot length 282 278 253 259 279 258 274 262 Height 1785 1771 1676 1646 1859 1710 1789 1737 State the Null and alternate hypotheses symbolically. Find the linear correlation coefficient Find the P-value State the decision State the conclusion If a linear correlation exists, find the regression equation. If no correlation exists, state that the regression equation is not a good model for the data. Find the best predicted height of a male with a foot length of 273.
