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 meets the pollution standard? Use α=0.01.

A major car manufacturer wants to test a new engine to determine whether it meets new air pollution standards.
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 major car manufacturer wants to test a new engine to determine
if it meets new air pollution standards. The mean emission, mu of
all engines of this type must be approximately 20 parts per million
of carbon. If it is higher than that, they will have to redesign
parts of the engine. Ten engines are manufactured for testing
purposes and the emission level of each is determined. Based on
data collected over the years from a variety of engines,...

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

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...

A video game manufacturer has recently released a new game. The
manufacturer wants to know whether players rate their new game as
more or less difficult than the average difficulty rating of all of
their games, μ = 6 and σ = 2. A random sample of 36 players yielded
a sample mean of 7 and a standard deviation(s) of 1.8.

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...
