Question 3: A
control chart requires independent repeated observations
over time. In addition, based on other factors,
different charts are appropriate. In the following
conditions identify one or more control charts that are
appropriate. If more than one control chart is
appropriate, the usual approach is to try both charts and
select the chart with tighter controls (i.e. control limits
with smaller absolute difference):
Is there one observation per time period? 
Is the observation measured on a continuous
(interval) scale? 
Are data outliers (values more than 2 standard
deviations away from mean)?

Question 4: In the following data, we have tracked
whether 352 infants in our prenatal clinic eventually
showed for various services in postnatal care. Each
clinic is reporting if these 352 patients showed at their
clinic and on what dates. Given these data, calcualte
the referral rate to each clinic. Has the rate of
daysofreferrals to ultrasound clinic, neurology
clinic, and combination of ultrasound and neurological
clinic changed over time? Note that if there is two or
more referrals on same day, you can count it as one day in
which there has been a referral. What is the daily
probability of referrals to each of these three clinics.
In analyzing these data you may wish to use combination of
if and match commands within excel. The command may
look like =if(match(A2, C:C, 0), 1,0). This command
says the value that should be matched is in A2, the lookup
array is in column C, and 0 indicates that it should be
exact match. Data►
Question 5: In the past 3 years, there have been
the following incidences of privacy violations: A
disgruntled employees sold information on May 11 of year 1.
Another disgruntled xemployee sold password to the system
on Dec 12 of year 3. There have been four incidences
of clinician discussing patient information in social
gathering on the following dates: December 5 year 2, January
25 Year 3, May 27 year 3, and September 1 year 3. Days of
incidences of any other types of privacy violations were May
11 year 1, Nov 22 year 2, Dec 27 year 3. Which types
of privacy violations are more frequent?
Construct a time between control chart for any privacy
violation. In analyzing these data you may wish to use
combination of if and match commands within excel. The
command may look like =if(match(A2, C:C, 0), 1,0).
This command says the value that should be matched is in A2,
the lookup array is in column C, and 0 indicates that it
should be exact match.
