True or false? The value zc is a value from the standard normal distribution such that P(−zc < z < zc) = c. True. By definition, critical values zc are such that 100c% of the area under the standard normal curve falls in the tails, to the left of −zc and to the right of zc. False. By definition, critical values zc are such that 100c% of the area under the standard normal curve falls between −zc and zc. True. By definition, critical values zc are such that 100c% of the area under the standard normal curve falls between −zc and zc. False. By definition, critical values zc are such that 100c% of the area under the standard normal curve falls in the tails, to the left of −zc and to the right of zc.
