Percentile of a normal distribution

[hard dawn]

How do I get the answer to d and e?

For d it's just the x-value under 95%, but does this mean the same thing as e?

Use inverse search, i.e. find the value that is the nearest to $0.95$, and obtain the corresponding z value: \
i.e. $P(Z < a) = 0.95 \Rightarrow Z < 1.645$ \
(Interpolation is generally not required in mathematics, but required in engineering. Choosing the nearest number is sufficient.)
