OOO+ B" Questions 1. What percentage of adolescents "Strongly Agree" to the statement that they believe they can make a difference in their communities? 43.2% strongly agree. 2. What is the margin of error (plus and minus) for the estimate of adolescents Who "Strongly Agree" to the statement that they believe they can make a difference in their communities? MOE 47.5- 43.2= 4.3 43.2- 38.9= 4.3 ** include +/- 4.3 3. What percentage of adolescents participate in one or more groups that make a difference? 41.4% 4. What is the margin of error (plus and minus) for the estimate of adolescents Who participate in one or more groups that make a difference? MOE 41.4 - 37.7= 3.7 45.2- 41.4= 3.8 ** include +/- 3.75 5. Are the estimates for Strongly Agree that they can make a difference and participating in one or more group that makes a difference statistically significantly different from each other? In other words, can you say that one groups is more or less than the other and have that supported by the data, including the confidence intervals?

Are the estimates of adolescents Who Strongly Disagree that they can make a difference and those Who do not participate in a group that makes a difference statistic ally significantly different from each other? In other words, can you say that one groups is more or less than the other and have that supported by the data, including the confidence intervals? 12. Explain your answer to #11, in terms of the margins of error for the two estimates. OOO
