Question 4
You may need to use the appropriate appendix table to answer this question. A production process is checked by a quality control inspector who periodically selects simple random samples of 50 finished products. For each sample the inspector computes x, the sample mean weight for the products. If, over a long period of time, the samples show that 5% of the sample means (x values) are over 1.1 pounds and 5% are under 0.9 pounds, what are the mean and the standard deviation of the distribution of weights (in lb) for the population of products produced with this process? Mean, rounded to one decimal: Standard deviation, rounded to 2 decimals: lb lb
Section 5.4 (please help with TI-84 calculator if possible) The lengths of lumber a machine cuts are normally distributed with a a mean of a 104 inches and a standard deviation of 0.5 inch. (A) what is the probability that a randomly selected board cut by the machine has a length greater than 104.23 inches? (B) A sample of 40 boards is randomly selected. What is the probability that their mean length is greater than 104.23 inches? (A) The probability is ________ (B) The probability is________ (Round to 4 decimal places as needed)

Question 16: A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 249.7-cm and a standard deviation of 1.1-cm. For shipment, 18 steel rods are bundled together. Find the probability that the average length of a randomly selected bundle of steel rods is less than 250.2-cm. Write your answer as a number accurate to 4 decimal places.
Question 4 According to a study done by Pierce College JBLM, the height for Hawaiian adult males is normally distributed with an average of 66 inches and a standard deviation of 2.5 inches.
