In a recent year (365 days), there were 690 murders in a city. Find the mean number of murders per day, then use that result to find the probability that in a single day, there are no murders. Would 0 murders in a single day be a significantly low number of murders? The mean number of murders per day is El. (Round to one decimal place as needed.) The probability that in a single day, there are no murders is '1. (Round to three decimal places as needed.) Would 0 murders in a single day be a signicantly low number of murders? Yes, because the probability is greater than 0.05. Yes, because the probability is 0.05 or less.. No, because the probability is 0.05 or less. No, because the probability is greater than 0.05
