Given that,
mean =
= 1.00
standard deviation =
= 0.01
Using standard normal table
P(Z < z ) = 99%
P(Z < z ) = 0.99
P(Z < 2.326 ) = 0.99
z = 2.326
Using z-score formula,
x = z *
+
x = 2.326 * 0.01 + 1.00
x = 1.02 in.

The diameter of shafts turned on a lathe are considered to be normally distributed, with a mean of 1.00 in. and a standard deviation of 0.01 in. What is the probability that a given shaft will have a diameter above 1.015 in.?
A particular manufacturing design requires a shaft with a diameter of 24.000 mm, but shafts with diameters between 23.991 mm and 24.009 mm are acceptable. The manufacturing process yields shafts with diameters normally distributed, with a mean of 24.004 mm and a standard deviation of 0.004 mm.Complete parts (a) through (d) below. a. For this process, what is the proportion of shafts with a diameter between 23.991 mm and. 24.000 mm? b. For this process what is the probability that...
A particular manufacturing design requires a shaft with a diameter of 18.000 mm, but shafts with diameters between 17.987 mm and 18.013 mm are acceptable. The manufacturing process yields shafts with diameters normally distributed, with a mean of 18.005 mm and a standard deviation of 0.004 mm. Complete parts (a) through(d) below. a. For this process, what is the proportion of shafts with a diameter between 17.987 mm and 18.000 mm? b. For this process, what is the probability that...
A particular manufacturing design requires a shaft with a diameter of 23.000 mm, but shafts with diameters between 22.992 mm and 23.008 mm are acceptable. The manufacturing process yields shafts with diameters normally distributed, with a mean of 23.005 mm and a standard deviation of 0.004 mm. Complete parts (a) through (d) below. (Round to four decimal places as needed.) c. For this process, what is the diameter that will be exceeded by only 0.5% of the shafts? The diameter...
The diameter of an electric cable is normally distributed, with a mean of 0.8 inch and a standard deviation of 0.01 inch. What is the probability that the diameter will exceed 0.81 inch? (You may need to use the standard normal distribution table. Round your answer to three decimal places.)
A) The diameters of pencils produced by a certain machine are normally distributed with a mean of 0.30 inches and a standard deviation of 0.01 inches. What is the probability that the diameter of a randomly selected pencil will be between 0.21 and 0.29 inches? B) The diameters of pencils produced by a certain machine are normally distributed with a mean of 0.30 inches and a standard deviation of 0.01 inches. What is the probability that the diameter of a...
The diameters of ball bearings are distributed normally. The mean diameter is 99 millimeters and the standard deviation is 5 millimeters. Find the probability that the diameter of a selected bearing is greater than 109 millimeters. Round your answer to four decimal places.
a particular manufacturing design requires a shaft with a diameter between 23.92 and 24.018 mm. The manufacturing process yields shafts with diameters normally distributed, with a mean of 24.003 and standard deviation of .006. a) for this process what is the proportion of shafts with a diameter between of 23.92 and 24.00 mm b) The probability that the shaft is acceptable is _ c) The diameter that will be exceeded by only.5% of shafts is - a particular manufacturing design...
