Student did repeated measurements of the coefficient of friction,
which is a dimensionless quantity. The mean of the measurements is
\(0.6\) and the coefficient of
variation (relative error) \(10\%\).
From statistics it is known that with a probability nearly
\(100\%\) the
value of the coefficient is in the interval centered at the mean and having radius equal
to the triple of the standard deviation. Find the upper bound of this interval.
