Question

At a certain fire station, false alarms are received at a mean rate of .2 per day. In a year, what is the probability that fewer than 48 false alarms are received? Note: You may need to use Excel to calculate the exact probability if the z-score is not in the book's tables. (Consider 365 days a year. Round your standard deviation value to 3 decimal places and z-value to 2 decimal places. Round your final answer to 4 decimal places.)

Probability           __________

Step 1

Introduction:

The mean rate of receiving a false alarm per day is 0.2. Thus, the mean rate of receiving a false alarm per year is 0.2 × 365 ...
