Answer:
Given by:
here,
The diameter of 3 inches
The standard deviation of the process of 0.3 inches
so that here,
"The correct option is c"
In control , because none of the three warning signals detected a change
A gear has been designed to have a diameter of 3 inches. The standard deviation of the process is 0.3 inch. A control chart is shown. Each chart has horizontal lines drawn at the mean, μ, μ 2o, and a...
better quality image O Is the process in control or out of control? Choose the correct answer below. A liquid-dispensing machine has been designed to fill bottles with 10 liter of liquid. The standard deviation of the process is 0.2 liter. A control chart is shown. The chart has horizontal lines drawn at the mean, H. att 20, and at 30. Determine if the process shown is in control or out of control. Explain. Liquid Dispenser Liquid dispensed (in ters)...
A control chart is used for monitoring a process meanl (X) that is normally distributed with a mean of μ and a standard deviation of σχ , and the sample size is n-5. А 3-sigma limit (μ ±30% ) is used as control limits. Two decision rules are given here. Rule 1: If one or more of the next seven samples yield values of the sample average that fall outside the control limits, conclude that the process is out of...
6.1.6. A process for making steel pipe is under control if the diameter of the pipe has mean 3.0 in. with standard deviation of no more than 0.0250 in. To check whether the process is under control, a random sample of size n 30 is taken each day and the null hypothesis 3.0 is rejected if X is less than 2.9960 or greater than 3.0040. Find (a) the probability of type I error; (b) the probability of type II error...
Piston rings for an automotive engine are produced by a forging process. We wish to monitor the inside diameter of the rings manufactured by this process, using an x̄ and an s control chart. Samples of size 8 are to be taken at regular intervals, and the sample means and standard deviations are computed and plotted on the charts in time order. The target values for the inside diameter are a mean of μ = 75 mm and a standard...
