Suppose \(X\) represents the noise level (in decibels) of a crowd at a school concert, and it follows a normal distribution with a mean of 85 decibels and a standard deviation of 15 decibels. The sound engineer sets a microphone threshold such that 60\(\pourcent\) of the time, the noise is below this level. Using a
, find this noise level (i.e., the 60th percentile). Round your answer to one decimal place.
\(x \approx\)
