Diketahui	\(\hat \mu = 7,398169905\) \({\hat \sigma ^2} = 0,4054651081\)
Rumus	\(P(X < x) = \Phi \left( {\frac{{\ln x – \mu }}{\sigma }} \right)\)
Proses Pengerjaan	\(P(X > 4.500) = 1 – P(X < 4.500)\) \(P(X > 4.500) = 1 – \Phi \left( {\frac{{\ln 4.500 – 7,398169905}}{{\sqrt {0,4054651081} }}} \right)\) \(P(X > 4.500) = 1 – \Phi \left( {1,59} \right)\) Dilihat pada tabel distribusi normal saat z=1,59 yaitu 0,9441 \(P(X > 4.500) = 1 – 0,9441\) \(P(X > 4.500) = 0,0559\) \(P(X > 4.500) \cong 0,056\)
