How do Americans think about ads on websites? A survey of 1,000 adult Internet users found that 670 opposed ads on websites. Assume that the survey of 1,000 Internet users age 12-17 found that 510 opposed ads on websites. At 0.05 level of significance, is there evidence of difference between adult Internet users and Internet users age 12-17 in proportion who opposes ads? Solve manually and then by mega stat. Point to your decision rule, your hypotheses and statistical and management conclusions."
