Suppose X has a symmetric continuous probability distribution with E(X)=82, and P(X>100) =0.2, what is P(64<X<100)? (Hint: Remember E(X) or expected value of X, is the average of X) A. 0.2 B. 0.3 C. 0.4 D. 0.6
Suppose x has a distribution with μ = 82 and σ = 9. (a) If random samples of size n = 16 are selected, can we say anything about the x distribution of sample means? Yes, the x distribution is normal with mean μx = 82 and σx = 0.6.No, the sample size is too small. Yes, the x distribution is normal with mean μx = 82 and σx = 2.25.Yes, the x distribution is normal with mean μx = 82...
