6. Earthquake intensities are measured using a device called a seismograph, which is designed to be most sensitive to earthquakes with intensities between 4.0 and 9.0 on the Richter scale. Measurements of nine earthquakes are given as follows: 5.5 L 6.5 H 8.7 8.9 6.0 H 5.2 where L indicates that the earthquake had an intensity below 4.0 and an H indicates that the earthquake had an intensity above 9.0. The median earthquake intensity of the sample is а. 5.75 b. 6.00 с. 6.50 d. 8.70 7. Which is a correct statement regarding a weighted mean? The weighted mean is less affected by outliers than the median. b. Multiply the weighting by the corresponding data value, then find the sum of the products. A weighted mean is always different from the actual mean. а. C. d. A weighted mean accounts for the relative importance of each value in the average. 8.
