Answer:
a) P (x is less than 11 minutes) = 0.55
P (x is more than 14 minutes) = 0.3
b) P (x is between 8 and 13 minutes) = 0.25
c) P(x < c) =0.8 is 0.05 x c = 0.8
Step-by-step explanation:
a) P (x is less than 11 minutes) = 11 x 0.05
= 0.55
P (x is more than 14 minutes) = 0.05 x (20 - 14)
= 0.05 x 6
= 0.3
b) P (x is between 8 and 13 minutes) = 0.05 x (13 -8)
= 0.05 x 5
= 0.25
c) P(x < c) =0.8
The area between 0 and c is 0.8
Hence,
0.05 x c = 0.8
