Determine the value of z* such that it satisfies the conditions below. (Assume that the requested value of z* is positive. Round your answers to two decimal places.)

(a) −z* and z* separate the middle 95% of all z values from the most extreme 5%.
z* =  

(b) −z* and z* separate the middle 92% of all z values from the most extreme 8%.
z* =  

(c) −z* and z* separate the middle 97.8% of all z values from the most extreme 2.2%.
z* =

Refer to slide 11 in the PowerPoint deck 13. Look at the examples below and determine whether the conditions for the estimation of the mean are met, and if so, whether it is appropriate to look up the critical values from the normal (z) or Student’s t (t) distributions, and look up the appropriate critical values. If the conditions are not met, indicate that none of these is applicable: Confidence level Sample size N Population standard deviation Distribution shape Z...
