A police commissioner is interested in the number of phone calls into the police dispatcher that result in criminal charges actually being filed. For a random sample of 190 nights (7 pm to 7 am), the following information was obtained where x = number of calls resulting in criminal charges and f = frequency with which this many calls occurred (i. e., number of nights). x 25 26 27 28 29 30 31 32 33 34f 11 16 17 22 24 17 23 26 21 13Assuming these 190 nights represent the population of all nights in this police precinct, what do you estimate the probability is that on a randomly selected night, there will be from 25 to 29 (including 25 and 29) calls to the dispatcher that result in criminal charges being filed?
