Using Minitab, solve the following problem. A process that produces parts for auto-mobile turbocharger wheels is to be controlled though the use of a fraction nonconforming chart. Initially, one sample of size 100 is taken each day for 20 days, and the results shown in table are observed Day Nonconforming units Day Nonconforming units 1 3 11 2 2 2 12 4 3 4 13 1 4 2 14 3 5 5 15 6 6 2 16 0 7 1...
Final Project For this assignment, use data from W1 Assignment. Using Minitab. Give instructions on how to insert data into Minitab. This week, you will explore the hypothesis that higher levels of stress are associated with lower levels of confidence. Compute the correlation between the stress score and confidence scores.

The Take-Charge Company produces batteries. From time to time a random sample of six batteries is selected from the output and the voltage of each battery is measured, to be sure that the system is under control. Here are statistics on 16 such samples Sample Mean ļ Range 4.99 0.41 4.87 057 4.85 5.26 0.59 0.74 0.74 5.090.21 5 6 7 0.21 5.02 5.13 5.09 5.01 30.56 0.92 0.49 9 10 5.19 0.56 5.40 0.44 12 13 14 15 5.15...

Problem 6. The set (Z19 − {0}, ·19) is a group with the
indicated operation; see the attached table. a.) Show that H = {1,
7, 8, 11, 12, 18} is a subgroup. b.) List all the right cosets of
H. c.) Show that if Hy = Hx then xy−1 ∈ H. [Make sure to give a
reason for each step.] d.) Show that φ : H → Hx defined by φ(h) =
hx is one-to-one and onto. [Use the...
Judy Holmes Industries has decided to use a p-Chart to monitor the proportion of defective castings produced by their production process. The control limits on these charts will be designed to include 95%95% of the sample proportions when the process is In Control. The operations manager randomly samples 400400 castings at 1616 successively selected time periods and counts the number of defective castings in the sample. Table Control Chart Copy Table Step 8 of 8 : You, acting as the...
Data was collected from a textile finishing process. Samples were collected daily and the number of nonconformities were recorded.

The dataset below is the observed number of defects from inspecting 25 successive wafers each containing n= 100 chips. Here the wafer is the inspection unit. (a) Create the appropriate control chart to control the data. (b) From the control chart, would you conclude that the process is in statistical control? (c) If any out of control points by Western Electric runs rule 1 are observed, assume they have assignable causes and can be omitted from control limit estimates. Create...
