KExercise 3.43) According to a Los Angeles Times study of more than 1 million medical dispatches from 2007 to 2012, the 911 response time for medical aid varies dramatically across Los Angeles (LA Times website, November 2012). Under national standards adopted by the Los Angeles Fire Department, rescuers are supposed to arrive within six minutes to almost all medical emergencies. But the Times analysis found that in affluent hillside communities stretching from Griffith Park to Pacific Palisades, firefighters failed to hit that mark nearly 85% of the time. The following data show the response times, in minutes, for 10 emergency calls in the Griffith Park neighborhood 11.8 Based on this sample of ten response times, compute the following descriptive statistics a. Mean, median, and mode Mean 10.3 10.7 10.6 11.5 8.3 10.5 10.9 10.7 11.2 (to 2 decimals) (to 1 decimal) (to 1 decimal) 10.65 Median Mode b. Range and standard deviation Range 10.7 10.7 (to 1 decimal) Standard deviation (to 4 decimals)Explanation / Answer
