QUESTION 25 1 point A baby dolphin is born into the ocean, which is a fairly cold environment. Water has a high heat conductivity, so the thermal regulation of a newborn dolphin is quite important. It has been known for a long time that baby dolphins' blubber its different in composition and quantity from the blubber of aduilts. Does this make the babies better protected from the cold compared to adults? One measure of the efflectiveness of blubber is its conductance. This value as calculated on 1 newborn dolphins and 10 adults dolphins (Dunkin et al. 2005) The newborn dolphins had an average conductance of 10.44, with a standard error of the mean equal to 0.8. The adult dolphins' conductance averaged 8.44, with the standard error of this estimate equal to 1.46. All measures are given in watts per square meter per degree Celcius Calculate the standard deviation of conductance for the adult dolphin group. Round your answer two decimal places.

Explanation / Answer

The mean of the data is 8.44.

The standard error = 1.03

Standard deviation = Se * Square root of Mean = 1.03 * root of 8 = 1.03 * 2.91 = 2.99

Therefore, standard deviation of conductance for adult dolphin groups is 2.99
