Assume that adults have IQ scores that are normally distributed with a mean of 104 and a standard deviation of 15. Find the third quartile Upper Q 3 , which is the IQ score separating the top 25% from the others. Click to view page 1 of the table. LOADING... Click to view page 2 of the table. LOADING... The third quartile, Upper Q 3 , is nothing . (Round to one decimal place as needed.)

z = (X-Mean)/SD

X = Mean + (z*SD)

The z value which separates the bottom 75% (100%-25%) from the top 25% is + 0.6745

Therefore, Q3 = X = 107 + (0.6745*16) = 117.8

Step-by-step explanation:

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
