Truc or False Circle the appropriate answer Explanations arc
Truc or False. Circle the appropriate answer. Explanations arc NOT required. If the events A and B an? mutually exclusive, then they are independent. If P(A) = 0.5, P(tf) = 0.5 and P(A^C and B^c) = 0.5 then P(A|B) = 1. If the sample variance of a set of data is equal to 0, then all values in the sample must be equal. If the random variable X has a normal distribution with mean n and variance sigma^2 then the median of X Is mu. If X and Y are independent, E(X^2) + E(Y^2) - E(X)^2 + E(Y )^2 As your sample size n gets large, the sampling distribution of X\\, the first observation in your sample, approaches a Normal distribution with mean mu and variance sigma^2. The first quartile cannot be greater than the median.
