The Youth Risk Behavior Survey (a study of public high school students) showed that 45 of 675 girls and 103 of 621 boys had been in a physical fight on school property one or more times during the past 12 months Using 5% significance, perform an appropriate test of hypothesis that the proportion of girls involved in a physical fight on school property is less than the proportion of boys involved in a physical fight on school property. Step 1: H0: ________________ Ha: ____________________ Significance level α =0.05 Step 2: Check necessary data conditions and compute an appropriate test statistic: Step 3: Compute corresponding p-value
