A reasonable value of the correlation coefficient r for thes

A reasonable value of the correlation coefficient r for these data is 1.2.

If the weight (WT) were measured in kilograms instead of pounds (1 lb = 0.4536 kg) the value of r would change accordingly.

If the outlier were removed, the correlation coefficient (r) would increase.

If the outlier were removed, the correlation coefficient (r) would decrease.

Solution

A reasonable value of the correlation coefficient r for these data is 1.2. [FALSE. The maximum value for r is 1.]

If the weight (WT) were measured in kilograms instead of pounds (1 lb = 0.4536 kg) the value of r would change accordingly. [FALSE. conversions do not change r]

If the outlier were removed, the correlation coefficient (r) would increase. [TRUE, because the trend would be more consistent in that case]

If the outlier were removed, the correlation coefficient (r) would decrease. [FALSE]
