waiting time to see a doctor in a large clinic are normally distributes with a mean of 68.2 mins and a standard deviation of 14.8 mins (a). what is the probility that the waiting time to see a doctor is exactly 30 mins(b)probability to see a doctor between 60 and 80 mins (c)90 percent of the patients will wait more than what amount of timeto see a doctor

P (X = 30) = 0(because this is continuous distribution and probaiblity at eachpoint is zero. Only probability in an interval can be positive.)P (X = 30) = 0 B P (60 < X < 80) Normal...
