In the studies, old mice (equivalent to about a 70-year-old person) were randomly assigned to receive blood plasma either from a young mouse (equivalent to about a 25-year-old person) or another old mouse. The mice receiving the young blood showed multiple signs of a reversal of brain aging. One of the studies measured exercise endurance using maximum treadmill runtime in a 90-minute window. The results are given in the side-by-side boxplots in the figure below. 20 70 1Sanders L. "Young blood proven good for old brain". Science News, 185(11), May 31, 2014.

(a) Estimate the median runtime for the mice receiving old blood. Round your answer to the nearest integer. The median runtime for the mice receiving old blood is 1 minutes. e Textbook and Media (b) Do we expect the mean runtime for the mice receiving old blood to be larger than, smaller than, or about the same as the median for these mice? O About the same as the median runtime.
