You want to estimate the proportion of kids between the ages of 12 and 15 who have tried marijuana. you take a random sample of 130 maryland students and find that 23% of the sample report having tried marijuana. last year, the federal government ran a much larger survey of 10,000 students and found that 29% reported ever using marijuana. test the null hypothesis that the true population proportion of maryland students who have smoked marijuana is 29% versus the alternative hypothesis that it is different than that. use a 3% significance level. interpret your result.
