You are measuring blocks coming off of your manufacturing line, and you measure your mean as 8 cm and your standard deviation as 0.5 cm. What percentage of the blocks will be between 7.5 cm and 8.5 cm
Added by Julia C.
Step 1
- For 7.5 cm: z = (7.5 - 8) / 0.5 = -1 - For 8.5 cm: z = (8.5 - 8) / 0.5 = +1 Show more…

Suppose that a new version of the product is released which has looser tolerances. Also suppose that management had enough foresight to re-center the manufacturing process to 10 cm and lowered the standard deviation to 0.25 cm. Further suppose that the new tolerances are between 9.5 and 10.25; use P(X<=9.5) = 0.0228 and P(X<=10.25) = 0.8413 to find the percentage of beams that are produced on the new process that meet the new requirements. Round your answer to four decimal points.

A manufacturing process produces items with a mean length of 5 cm and a standard deviation of 0.1 cm. The lengths are normally distributed. If an item is randomly selected, what is the probability that it will have a length between 4.8 cm and 5.2 cm?
