Question 1 (a) In a metal fabrication process, metal rods are produced that have an average length of 20.5 feet with a standard deviation of 2.3 feet. A quality control specialist collects a random sample of 30 rods and measures their lengths. (i) Describe the sampling distribution for the sample mean by naming the model and telling its mean and standard deviation. [3 marks] (ii) Calculate the probability that the sample mean length of metal rods is less than 19.5...
