Reducing scrap of 4-foot planks of hardwood is an important
factor in reducing cost at a wood-flooring manufacturing company.
Accordingly, engineers at Lumberworks are investigating a potential
new cutting method involving lateral sawing that may reduce the
scrap rate. To examine its viability, samples of 500 and 400
planks, respectively, were examined under the old and new methods.
Sixty-five of the 500 planks were scrapped under the old method,
whereas 33 of the 400 planks were scrapped under the new method.
(You may find it useful to reference the appropriate
table: z table or t
table)
a. Construct the 99% confidence interval for the
difference between the population scrap rates between the old and
new methods, respectively. (Negative values should be
indicated by a minus sign. Round intermediate calculations to at
least 4 decimal places and final answers to 2 decimal
places.)
b. Select the null and alternative hypotheses to
test for differences in the population scrap rates between the old
and new cutting methods, respectively.
H0: p1 − p2 = 0; HA: p1 − p2 ≠ 0
H0: p1 − p2 ≤ 0; HA: p1 − p2 > 0
H0: p1 − p2 ≥ 0; HA: p1 − p2 < 0
c. Using the part a results, can we conclude at
the 1% significance level that the scrap rate of the new method is
different than the old method?

Reducing scrap of 4-foot planks of hardwood is an important factor in reducing cost at a wood-flooring manufacturing company. Accordingly, engineers at Lumberworks are investigating a potential new cutting method involving lateral sawing that may reduce the scrap rate. To examine its viability, samples of 600 and 500 planks, respectively, were examined under the old and new methods. Sixty-two of the 600 planks were scrapped under the old method, whereas 34 of the 500 planks were scrapped under the new...

IMPORTANCE Clinical outcomes for glioblastoma remain poor. Treatment with immune checkpoint blockade has shown benefits in many cancer types. To our knowledge, data from a randomized phase 3 clinical trial evaluating a programmed death-1 (PD-1) inhibitor therapy for glioblastoma have not been reported. OBJECTIVE To determine whether single-agent PD-1 blockade with nivolumab...
Because of its inability to control film and personnel
costs in its radiology department, Sanger General Hospital wants to
replace its existing picture archive and communication (PAC) system
with a newer version. The existing system, which has a current book
value of $2,250,000, was purchased three years ago for $3,600,000
and is being depreciated on a straight-line basis over an
eight-year life to a salvage value of $0. This system could be sold
for $800,000 today. The new PAC system...
