Find the area of the shaded region. The graph to the right depicts IQ scores of adults, and those scores are normally distributed with a mean of 100 and a standard deviation of 15 the area on the left is 75 and on the right is 120 i need the shaded area in the middle saying this because my graph may not show up . |
Solution :
Given that ,
mean = = 100
standard deviation = = 15
Using z table,
P(75< x <120 ) = P[(75 - 100) /15 < (x -) / < (120 - 100) /15 )]
= P( -1.67< Z <1.33 )
= P(Z <1.33 ) - P(Z <-1.67 )
Using z table,
=0.9082 - 0.0475
=0.8607
answer =0.8607
