A) Consider a sample X, X,X, of normally distributed random variables with variance o= 41. Suppose that n = 41. What is the value of c for which P(S² 2c) =0.50? (ii) What is the value of c for which P(S' <c) = 0.50? (i) B) Consider a sample x,,X,.,X, of normally distributed random variables with mean u. Suppose that n = 11. (i) What is the value of c for which P( (X – 4)/S 2c) = 0.50? (ii) What is the value of c for which P((X- 4)/S| sc)=0.56. Use Excel to calculate different statistical measures.
