Question 2 a) How many measurements in a data set subject to random errors lie outside deviation boundaries of +o and -o, that is, how many measurements have a deviation greater than | ? (assume Gaussian distribution) b) A box contains 105 transistors. The transistors have a mean current gain of 20 and a standard deviation of 2. Assume Gaussian distribution. Calculate the following: i. number of transistors with a current gain between 19.8 and 20.2 ii. number of transistors with a current gain greater than 17
