Question 1186932: A psychologist interested in the intelligence of children develops a standardized test for selecting “gifted” children. The test scores are normally distributed, with µ = 75 and σ = 8. Assume a gifted child is defined as one who scores in the upper 1% of the distribution.

You can put this solution on YOUR website! z(0.99)=2.326--2ndVARS3invnorm(0.99,0,1) ENTER
z=(x-mean)/sigma
2.326=(x-75)/8
18.61=x-75
x=93.61
