21 Consider the following statements: iGiven that Z is a standard normal variable, its values are always between -3 and +3. 1i. Given that Z is a standard normal random variable, P(Z=1.25) = P(Z=-1.25) = 0.3944 i11 For any symmetric distribution, the mean, median, and mode will have the same value. iv.In the standard normal distribution, Zo os = 1.645 means that 5% of all values of Z are below 1.645 and 95% are al Which of the following is correct about the statements?
