Question

 The waiting times to see a doctor at a health centre is normally distributed with ?~?(30, 52). Find the probability that a random selected patient waits:

(i) no more than 35 minutes to see the doctor. 

(ii) between 35 and 40 minutes to see the doctor.  

 

Standard Normal Values for ?~?(0,1)

?(? € 0) = 0.5

?(? € 1.0) = 0.8413

?(? € 2.0) = 0.9772

?(? € 2.50) = 0.9938
