A textile manufacturing process finds that on average, five flaws occur per every 90 yards of material produced.

a. What is the probability of exactly one flaws in a 90-yard piece of material? (Do not round intermediate calculations. Round your final answer to 4 decimal places.)



b. What is the probability of no more than two flaws in a 90-yard piece of material? (Do not round intermediate calculations. Round your final answer to 4 decimal places.)



c. What is the probability of no flaws in a 72-yard piece of material? (Do not round intermediate calculations. Round your final answer to 4 decimal places.)

The number of flaws per square yard in a type of carpet material varies with mean 1.3 flaws per square yard and standard deviation 1 flaws per square yard. This population distribution cannot be normal, because a count takes only whole-number values. An inspector studies 167 square yards of the material, records the number of flaws found in each square yard, and calculates x, the mean number of flaws per square yard inspected. Use the central limit theorem to find...

Items produced by a manufacturing process are supposed to weigh 90 grams. However, there is variability in the items produced, and they do not all weigh exactly 90 grams. The distribution of weights can be approximated by a normal distribution with a mean of 90 grams and a standard deviation of 1 gram. To monitor the production process, items are sampled from the manufacturing process and weighed several times throughout each day. What proportion of all possible items will either...
