Hi  

'Standard Distribution': µ = 32.4 and σ =13.7
n 107
 {{{ME = z*sigma/sqrt(n)}}}
 90% confidence interval:  z = 1.645  |  Invnorm(.9 + .1/2) = Invnorm(.95) 
  {{{ME =1.645*13.7/sqrt(107)}}} = 2.179
32.5 - 2.179 {{{mu}}} < 32.5+ 2.179
30.321 {{{mu}}} < 34.679

90% confident,  interval will contain true population mean

Wish You the Best in your Studies.
