Round these answers to two places after the decimal: Test-statistic = ( ) (to two places after the decimal) P-value =( ) (to four places after the decimal) There (is/is not) sufficient evidence to conclude that the proportion of students using marijuana is lower for students exposed to the DARE program
A study compared the drug use of 288 randomly selected high school seniors exposed to a drug education program (DARE) and 335 randomly selected high school seniors who were not exposed to such a program. Data for marijuana use are given in the accompanying table.
number who use marijuana | ||
---|---|---|
exposed to DARE | 288 | 139 |
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?
