A biologist is studying the gestation period of domestic dogs. Fifteen dogs are observed during pregnancy and are found to have the following periods, in days.
62.0 61.4 59.8 62.2 60.3
60.4 59.4 60.2 60.4 60.8
61.8 59.2 61.1 60.4 60.9
A. Compare the sample mean with sample median. What do you think about the shape of the histogram? Please explain.
B. a gestation period less than 50 days is consider premature. Suppose that the data actually includes a 16th observation which is a premature gestation period, but the exact number is missing. Will the sample median change? If so, what is the new sample median?
