A dog gave birth to 4 puppies. Three of the puppies had different masses between 145 and 157g, and one puppy had a mass of 59g.
The puppy that had a mass of 59g was then adopted, so that puppy was removed from the data set.
How will the removal of the puppy affect the mean and median?

A group of Americans participated in a study that involved taking their temperatures during exercise is moderate heat. The participants had a mean body temperature of 104 degrees F and a standard deviation of 2 degrees F.
Doctors analyzing the results prefer to work in degrees Celsius, so they convert the data by applying the formula below to each data point:
If each temperature is converted to degrees Celsius, what will be the mean and standard deviation of the distribution of new temperatures?
