Question 1:

Working:

**Now the answer for sigma i got correct, but μ i got incorrect for some reason. Could anyone explain where I've gone wrong for μ?**

Question 2:

Workings:

All i need help is with part c and d:

for c) i done 1 - 0.6463 to get the probability of the two shaded bits, but where do i go to get the part they are asking for?

for d) i have no idea, any help would be great.

thanks.
