How do I do these computations without a normal distributionchart and just a TI84 calculator?
6.7 Given a standard normal distribution, ï¬nd the value of ksuch that
(a) P(Z>k)=0 .2946;
(b) P(Z
(c) P(−0.93
6.8 Given a normal distribution with μ = 30 and σ = 6, ï¬nd
(a) the normal curve area to the right of x = 17;
(b) the normal curve area to the left of x = 22;
(c) the normal curve area between x = 32 and x = 41;
(d) the value of x that has 80% of the normal curve area to theleft;
(e) the two values of x that contain the middle 75% of thenormal curve area.
