Data for marijuana use are given in the accompanying table. sample size number who use marijuana exposed to DARE 288 138 not exposed to DARE 335 181

At the 5% significance level, is there convincing evidence that the proportion using marijuana is lower for students exposed to the DARE program?

Round these answers to two places after the decimal: Test-statistic =

P-value = (to four places after the decimal)

There is not sufficient evidence to conclude that the proportion of students using marijuana is lower for students exposed to the DARE program.

There is not sufficient evidence to conclude that the proportion of students using marijuana is lower for students exposed to the DARE program, since p-value is greater than the 0.05 significance level.
