Q.3.2 Experience has shown that the diameter of a particular engineering component is normally distributed, with an average diameter (u) of 45mm and a standard deviation (o) of 3mm. A sample of 85 of these components is selected. Q.3.2.1 Determine the standard error for this sample. Q.3.2.2 What is the probability that the mean diameter of the components in the sample lies between 44.50mm and 45.75mm? Interpret your answer.
