Extracted text: 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 is different in composition and quantity from the blubber of adults. Does this make the babies better protected from the cold compared to adults? One measure of the effectiveness of blubber is its "conductance". This value as calculated on 6 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 0.51. The adult dolphins' conductance averaged 8.44, with the standard error of this estimate equal to 1.81. All measures are given in watts per square meter per degree Celcius. Calculate the standard deviation of conductance for the baby dolphin group. Round your answer two decimal places. In order to test if the mean from Population A is greater than the mean from Population B what kind of t-test would you use? one-tailed t-test unpaired t-test two-tailed t-test paired t-test one-sample t-test
