For Problem 19.39 , determine the probability (assuming normal distribution) that a tire could be used reliably for less than 45,000 kilometers.
Concrete blocks are manufactured for construction. Assume the weights of the manufactured concrete blocks are normally distributed with a mean value of μ= 11.0 kg and a standard deviation of σ = 0.3 kg. a. As an engineer, what rangeof weights do you expect to find in 99.3% of the population? b. In a batch of 200 blocks, how many blocks do you expect to weigh less than 10.49 kg? c. Draw a normal probability distribution labeling the mean and the horizontal axis. Shade in the percent less than 10.49 kg.
