The current advertising campaign for a major soft drink brand would be changed if less than 30 percent of the consumers like it. A random sample of 300 consumers was surveyed, and 84 respondents indicated that they liked the campaign, equivalent to 28%. What are the null and alternative hypothesis? If the test-statistic is calculated to be -0.7407, at significance level of 5% with critical value of 1.64, can we reject the null and say we should the campaign be changed?
