An electronic product takes an average of 6 hours to move through an assembly line. If the standard deviation of 0.9 hours, what is the probability that an item will take between 5.9 and 7.3 hours to move through the assembly line? Do not round until you get your your final answer, and then round to 3 decimal places. Answer Question 12 Points possible: t This is attempt 1 of 3 (Round your answer to 3 decimal places, and report a probability value between 0 and 1.) A population of values has a normal distribution with a 9.8 and 56.7. You intend to draw a random sample of size n 123. What is the mean of the distribution of sample means? My What is the standard deviation of the distribution of sample means? (Report answer accurate to 2 decimal places.) Question 13. Points possible: 1 This is attempt 1 of 3 A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 251.3-cm and a standard deviation of 2.5-cm. For shipment, 19 steel rods are bundled together. Find the probability that the average length of a randomly selected bundle of steel rods is between 250.6-cm and 252-cm. P(250.6-cm
