Q3) A. Determine the values of c, for the following normal probabilities (i) ( > ) = 0.7206 (ii) ( < < 2.12) = 0.6596 B. The length of car parts produced at a factory is normally distributed with mean 48 and standard deviation of 12 cm. If you randomly select a car part, calculate the probability that: (i) The length is more than 43.5 cm.

(ii) The length is between 49.3 and 50.2 cm

(iii) If you randomly select a sample of 225 car parts, what is the probability that the mean length for the sample is less than 46.8 cm?
