Question

A toy store that has a 12% market share launches a marketing campaign. At the end of the campaign period the company conducts a survey in order to assess whether its market share has increased. If this claim is to be tested, the null and alternative hypotheses are: H0 : p = 12% Ha : p > 12%

Quizplus · Accepted Answer
