To determine

Explain the similarities between the Shewhart cycle and DMAIC.

Explanation of Solution

The Shewhart cycle is usually called as PDSA which is the combination of “Plan”, “Do”, “Study” and “Act”. It is an iterative process and require many cycles to solve complex problems.

In a six-sigma process, the Shewhart cycle is known as DMAIC, which is the combination of “Define”, “Measure”, “Analyze”, “Improve”, and “Control”. This procedure is used to complete projects by proceeding and providing permanent solutions. Moreover, it can be replicated in any business operations.

Both of these systems are searching ways to modify and improve the quality and processes.

Spam filters are built on principles similar to those used in logistic regression. We fit a probability that each message is spam or not spam. We have several variables for each email. Here are a few: to_multiple=1 if there are multiple recipients, winner=1 if the word 'winner' appears in the subject line, format=1 if the email is poorly formatted, re_subj=1 if "re" appears in the subject line. A logistic model was fit to a dataset with the following output:   Estimate SE Z Pr(>|Z|) (Intercept) -0.8161 0.086 -9.4895 0 to_multiple -2.5651 0.3052 -8.4047 0 winner 1.5801 0.3156 5.0067 0 format -0.1528 0.1136 -1.3451 0.1786 re_subj -2.8401 0.363 -7.824 0 (a) Write down the model using the coefficients from the model fit.log_odds(spam) = -0.8161 + -2.5651 + to_multiple  + 1.5801 winner + -0.1528 format + -2.8401 re_subj(b) Suppose we have an observation where to_multiple=0, winner=1, format=0, and re_subj=0. What is the predicted probability that this message is spam?…
