μ=47 hours and σ2=4.
\n" ); document.write( "a. 4invNorm(.98) + 47 = X,least amount of time these persons work per week
\n" ); document.write( "b.P(x ≤ 40) = normalcdf(-100,40,47,4)
\n" ); document.write( "c. 4invNorm(2.5)+47 = Xlow and 4invNorm(97.5) + 47 = Xhigh
\n" ); document.write( "c. P(45 < x < 55) = normalcdf(45,55,47,4)
\n" ); document.write( "e. normal(-100,42,47,4) + (49,100,47,4)
