1. Earthquake intensities are measured using a device called a seismograph, which is designed to be most sensitive for earthquakes with intensities between 4.0 and 9.0 on the open-ended Richter scale. Measurements of nine earthquakes gave the following readings: 4.5 L 5.5 H 8.7 8.9 6.0 H 5.2
L indicates that the earthquake had intensity below 4.0 and an H indicates that the earthquake had
intensity above 9.0. The median earthquake intensity of the sample is:
a. Cannot be computed since all of the values are not known
b. 6.47 c. 8.70 d. 5.75 e. 6.00
