<h2>Answer with explanation:</h2>

Let p represents the population proportion.

By considering the given information, we have

H_0: p=0.29\\\\H_a: p\neq0.29

∵ the alternative hypothesis is two tailed , so the test is two-tailed test.

Given : For sample size :n= 130,  \hat{p}=0.23

Test statistic: z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}

z=\dfrac{0.23-0.29}{\sqrt{\dfrac{0.29(1-0.29)}{130}}}\\\\=-1.50762993902\approx-1.51

P-value (two -tailed test)=2P(z>|-1.51|)=0.1310434\approx 0.131

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% .
