(Step-by-Step) The manufacturer of a propellant systems used in aircraft emergency escape , would like to say that his project has an average rate of combustion
Question:
The
manufacturer
of a propellant
systems
used in
aircraft emergency
escape
,
would like to
say that
his project has
an average rate of
combustion of
49.5
inches per minute
.
It assumes that
the combustion rate
is normally distributed
. He t
ry
20 grains
of propellant
selected
randomly
.
If the average
is
located
within
an interval with
a probability
of
90%
is satisfied.
A
conclusion
that
comes
with the following observations
?
49.02 49.91 50.84 48.05 50.03 49.83 51.19 49.08 50.25 50.31 50.24 49.23 49.20 49.88 49.78 50.64 49.74 49.51 50.76 50.17
