A process has an in-control fraction nonconforming of p =
0.02.
a) What sample size would be required for the fraction
nonconforming control chart if it is desired to have a probability
of a least one nonconforming unit in the sample to be at least
0.9?
b) Now assume n = 200. Establish a control chart for the
fraction nonconforming.
Use the data in the following table to create a fraction
nonconforming (p) chart. The column of
np represents the number of
non-conforming units. Is the process in control? (5 points)

Question 2
A bank's manager...
Which of the following t scores would significant at the
P<0.05 level not the P<0.01? There is more than 1.
Select one or more:
a. t = 2.89, df = 14
b. t = -2.87, df = 27
c. t = -2.17, df = 17
d. t = 3.52, df = 9
e. t = 2.68, df = 60
f. t = -2.93, df = 19

Give three examples of which type of health care setting you
would use HCPCS Level II coding. For each health care setting give
an example of a service that would be rendered in that setting.
Assume that you plan to use a significance level of \alphaα =
0.05 to test the claim that p1 = p2, Use the given sample sizes and
numbers of successes to find the pooled estimate p-bar. Round your
answer to the nearest thousandth. n1 = 236 n2 = 307 x1 = 77 x2 =
66
Assume that you plan to use a significance level of alpha = 0.05
to test the claim that p1 = p2. Use the given sample sizes and
numbers of successes to find the z test statistic for the
hypothesis test.
A report on the nightly news broadcast stated that 10 out of 108
households with pet dogs were burglarized and 20 out of 208 without
pet dogs were burglarized.
Which type of corporation (C or S) would you prefer as the
business owner? Which would you prefer as the taxpayer? Recall how
the income for each is treated to inform your response.
Assume that you plan to use a significance level of α = 0.05 to
test 5)
the claim that p1 = p2. Use the given sample sizes and numbers
of
successes to find the P-value for the hypothesis test, and make
a conclusion addressed to the claim.
