SOLUTION:
From given data,
The time required to assemble an electronic component is normally distributed with a mean and a standard deviation of 17 minutes and 9 minutes, respectively.
n=17
standard deviation(sd) = 9
a. Find the probability that a randomly picked assembly takes between 15 and 22 minutes.
b. It is unusual for the assembly time to be above 29 minutes or below 7 minutes. What proportion of assembly times fall in these unusual categories
Since the probability not less than 0.05, it is not unusual.
The proportion is 0.2253

electronic component is normally distributed with a standard
deviation of 4.5 minutes. If a random of 20 components is selected,
what is the probability that the standard deviation for the time of
assembly of these units is less than 3.0 minutes?

deviation of 600 hours. For a random sample of 25 components the
probability is 0.6915 that the sample mean lifetime is less than
how many hours?

A manufacturer of electronic kits has found that the mean time required for novices to assemble...
A manufacturer of electronic kits has found that the mean time
required for novices to assemble its new circuit tester is 2.8
hours, with a standard deviation of 0.6 hours. A consultant has
developed a new instructional booklet intended to reduce the time
an inexperienced kit builder will need to assemble the device and
the manufacturer needs to decide whether or not to send out the new
booklet.
The testable hypotheses in this situation are ?0:?=2.8H0:μ=2.8

The time required to complete a project is normally distributed
with a mean of 78 weeks and a standard deviation of 10 weeks. The
construction company must pay a penalty if the project is not
finished by the due date in the contract. If a construction company
bidding on this contract wishes to be 90 percent sure of finishing
by the due date, what due date (project week #) should be
negotiated?
The supervisor of a production line believes that the average time to assemble an electronic component is 18 minutes.
The supervisor of a production line believes that the average
time to assemble an electronic component is 18 minutes. Assume that
assembly time is normally distributed with a standard deviation of
4 minutes. The supervisor times the assembly of 19 components, and
finds that the average time for completion was 20.29 minutes. Is
there evidence that the average amount of time required to assemble
a component is something other than 18 minutes?What are the appropriate hypotheses one should test?H0: X...
