Let p represents the population proportion.
By considering the given information, we have

∵ the alternative hypothesis is two tailed , so the test is two-tailed test.
Given : For sample size :n= 130, 
Test statistic: 

P-value (two -tailed test)=
Since , the p-value (0.131) is greater than the significance level (0.03), so we accept the null hypothesis.
Thus , we conclude that we have sufficient evidence to support the null hypothesis that the true population proportion of Maryland students who have smoked marijuana is 29% .
