Assume that Z has a standard normal distribution. Use Appendix A Table I to determine the value for z that solves each of the following. (a) P(-z < Z < z) = 0.95 (Round your answer to two decimal places. And draw the standard normal distribution graph.
Added by Emily C.
Step 1
This means that if we want the probability between -z and z to be 0.95, we are looking for the z-value that leaves 0.025 (or 2.5%) in each tail of the distribution (because 1 - 0.95 = 0.05 and 0.05/2 = 0.025). Show more…

Assume $Z$ has a standard normal distribution. Use Appendix Table III to determine the value for $z$ that solves each of the following (a) $P(-z<Z<z)=0.95$ (b) $P(-z<Z<z)=0.99$ (c) $P(-z<Z<z)=0.68$ (d) $P(-z<Z<z)=0.9973$

Normal Distribution
Assume $Z$ has a standard normal distribution. Use Appendix Table III to determine the value for $=$ that solves each of the following: (a) $P(Z<z)=0.9$ (b) $P(Z<z)=0.5$ (c) $P(Z>z)=0.1$ (d) $P(Z>z)=0.9$ (e) $P(-1,24<Z<z)=0.8$
Given a standard normal distribution, find the area under the curve that lies (a) to the left of $z=-1.10$; (b) to the right of $z=1.645$; (c) between $z=-2.43$ and -0.45 ; (d) to the left of $z=0.45$; (e) to the right of $z=-0.45$; (f) between $z=-0.45$ and $z=0.45$.
