1. The problem statement, all variables and given/known data A cola company's long-term market share is estimated to be 45%. After an extensive advertising campaign, 68 out of 150 customers surveyed claimed to have purchased this company's cola recently. Was the advertising campaign a success? justify your assessment 2. Relevant equations Let m= mean and o=standard deviation p=probability of success q=probability of failure a=alpha, significance level 3. The attempt at a solution H0: m=0.45 H1: m<0.45 n=150 p=0.45 q=0.55 m=np =67.5 o=sqrt npq =6.09 x=68 a=0.01 S=o/sqrt(n) =6.09/sqrt(150) Z-sample: (68-67.5)/(6.09/sqrt(150)) =P(Z<1.01) =0.8438 I'm lost here. If this is right so far, where do I go next? I really don't even understand how I got this, basically just doing the same pattern that a note does. It's very vague though.
