A
major car manufacturer wants to test a new engine to determine if
it meets new air pollution standards. The mean emission u, of all
engines of this site must be approximately 20 ppm of carbon. if it
is higher than that they will have to redesign parts of the engine.
10 engines are manufactured for testing purposes in the emission
level of each is a determined. based on data collected over the
years from a variety of engines it seems reasonable to assume the
the mission levels are roughly normally distributed with standard
deviation=3 parts per million of carbon
1) what is the value of the P value?
0.0175
less than 0.0001
0.2525
0.9825
2) The data result in an average of 22 parts per million what
is the value of the test statistic?
z=2.11
z=6.67
z=0.667
z=-2.11

A major car manufacturer wants to test a new engine to determine
whether it meets new air pollution standards. The mean emission of
all engines of this type must be lower than 20 parts per million of
carbon. A number of engines are manufactured for testing purposes,
and the emission level of each is determined. The data (in parts
per million) are listed below:15.6, 16.2, 22.5, 20.5, 16.4, 19.4, 16.6, 17.9, 12.7, 13.9a). At 5% level of significance, is there...

A car manufacturer wants to test a new engine to determine
whether it meets new air pollution standard (true mean emission
must be less than 20 parts per million of carbon). Ten engines
manufactured for testing purposes yield the following emission
levels: 15.9, 16.2, 21.5, 19.5, 16.4, 18.4, 19.8, 17.8, 12.7, 14.8
Assume that the normal distribution assumption is satisfied for
this sample. Do the data supply sufficient evidence to allow the
manufacturer to conclude that this type of engine...

CHAPTER 10 LECTURE NOTES EXAMPLE #3
A car manufacturer wants to test a new engine to see whether it
meets new air pollution standards. The mean emission, μ, of all
engines of this type must be less than 20 parts per million of
carbon. Ten engines are manufactured for testing purposes, and the
mean and standard deviation of the emissions for this sample of
engines are determined to be:
X¯¯¯=17.1 parts per million s=3.0
parts per million n = 10X¯=17.1 parts
per...

The manufacturer of a new race car engine claims that the
proportion of engine failures due to overheating for this new
engine, (p1), will be no higher than the proportion of engine
failures due to overheating of the old engines, (p2). To test this
statement, NASCAR took a random sample of 140 of the new race car
engines and 145 of the old engines. They found that 14 of the new
race car engines and 11 of the old engines...

A manufacturer of widgets wants to test a new widget-producing
machine to determine if it can make an average of 20 widgets per
second before deciding to invest in the machine. The standard to
reject the new machine is if it makes an average of less than 20
widgets per second. Here are data from a small random sample:
15.6, 16.2, 22.5, 20.5, 16.4, 19.4, 19.6, 17.9, 12.7, 14.9
Assuming the population follows a normal distribution, is there
evidence that...

major car manufacturer is developing a
promotion that offers new car buyers the choice
between low interest financing at 0.9%
compounded monthly for 5 years or a cash
rebate. On a $30,000 car, what rebate makes
the buyer indifferent between the dealer’s
financing and taking the rebate and obtaining
bank financing at 4.6% compounded monthly for
the net cash price?

The manufacturer of a new racecar engine claims that the
proportion of engine failures due to overheating for this new
engine, (p1)(p1), will be no higher than the proportion of engine
failures due to overheating of the old engines, (p2)(p2). To test
this statement, NASCAR took a random sample of 115115 of the new
racecar engines and 165165 of the old engines. They found that 1212
of the new racecar engines and 66 of the old engines failed due to...
