hi..please help me to solve these problem. (15 marks) 3. Xi, X2, Xs, X4 is a random sample from the Normal (0, 4) distribution. We want to test HO: θ 15 versus Hi: θ< 15. Let X_13x (a) Suppose we have two decision rules: Reject Ho if and only if () X <IS (II) X <12 Which one is better and why? (b) Instead of n 4, let n be an unknown. Let the decision rule now be: Reject Ho...
=========================================== f=25.09 is wrong. Olestra is a fat substitute approved by the FDA for use in snack foods. Because there have been anecdotal reports of gastrointestinal problems associated with olestra consumption, a randomized, double-blind, placebo-controlled experiment was carried out to compare olestra potato chips to regular potato chips with respect to GI symptoms. Among 500 individuals in the TG control group, 16.6% experienced an adverse GI event, whereas among the 500 individuals in the olestra treatment group, 14.8% experienced such...
