According to a​ publication, 13.9​% of 18 to 25-year-olds were users of marijuana in 2000. A recent poll of 1366 randomly selected 18 to 25-year-olds revealed that 221 currently use marijuana. At the 1​% significance​ level, do the data provide sufficient evidence to conclude that the percentage of 18 to 25-year-olds who currently use marijuana has changed from the 2000 percentage of 13.9​%? Use the​ one-proportion z-test to perform the appropriate hypothesis​ test, after checking the conditions for the procedure. What are the hypotheses for the​ one-proportion z-test?   H0​: p=nothing​; Ha​: p ▼   greater than> less than< not equals≠ nothing ​(Type integers or​ decimals.) What is the test​ statistic?   z=nothing ​(Round to two decimal places as​ needed.) Identify the​ P-value.   The​ P-value is nothing. ​(Round to four decimal places as​ needed.)
