Question

True or false? The value zc is a value from the standard normal distribution such that P(–zc < z < zc) = c.

a. False. By definition, critical values zc are such that c% of the area under the standard normal curve falls between –zc and zc.

b. True. By definition, critical values zc are such that c% of the area under the standard normal curve falls between –zc and zc.

c. True. By definition, critical values zc are such that c% of the area under the standard normal curve falls in the tails, to the left of –zc and to the right of zc.

d. False. By definition, critical values zc are such that c% of the area under the standard normal curve falls in the tails, to the left of –zc and to the right of zc.

This is a Multiple Choice Question. The answer is not d. Please help me out, Thank you!
