0 You are working as a Quality Inspector in a firm. You are measuring lengths of some parts which are to be assembled into a machine. You have taken measurements for 150 parts. You find that the length of parts you measured follow a normal distribution with mean of 11 inches and standard deviation of 1.5 inches. Use this information and answer questions 2a to 2e. Question 11 Question a. Let X-length of a part (in inches). What is the distribution of X? OX-N(11) OX-N (11, 1.52) X-N(11.1.5) OX-Normal Question 12 Question b: What is the variance of X? 2.25 Question 13 Question c: What is the probability that length of the part is more than 12 inches (up to 4 digits)? 5 pts 5 pts 5 pts Text.
Question 14 Question d: What is the probability that the part length is between 10 and 12 inches(up to 4 digits)? Question 15 Question e: Find the part length x such that 2.5% of the measured parts have length greater then x(up to 2 digits). 5 pts 5 pts
