P(z > c) = 0.6592

Question

Find c rounded to two decimal places

Answer 1

P(z>c) = 0.6592

P(z>-.4103) = 0.65917

c = - .4103

c= -.41 rounded to 2 decimal places

use z tables or a z calculator

using the empirical rule

P(z>0) = .5

P(z>-1) = .5 + .68/2 = .5 + .34= .84

.5<.6592 < .84

c is somewhere between 0 and -1

-1 < c < 0

-.41 is in the right range
