1. In an experiment on the uptake of solutes by liver cells, a researcher found that six determinations of the radiation, measured in counts per minute after 20 minutes of immersion, were:
2728 2585 2769 2662 2876 2777
Construct a 99% con?dence interval for the population median and interpret its meaning.
2. The nominal resistance of a wire is 0.20 ohm. A testing of the wire randomly chosen from a large collection of such wires yields the following resistance data.
0.199 0.211 0.198 0.201 0.197 0.200 0.198 0.208
Obtain a 95% con?dence interval for the population median.
