Solution :
Given that ,
mean =
= 36
standard deviation =
= 10
n = 16
= 36
=
/
n = 10/
16 = 2.5
P(
>35 ) = 1 - P(
< 35)
= 1 - P[(
-
) /
< (35-36) /2.5 ]
= 1 - P(z <-0.4 )
Using z table,
= 1 - 0.3446
= 0.655
B.
Using standard normal table,
1ST quartile 25%
P(Z < z) = 25%
= P(Z < z) = 0.25
= P(Z <-0.67 ) = 0.25
z = -0.67
Using z-score formula
= z *
+
= -0.67*2.5+36
=34.3250
