The standard deviation for the resting heart rates of Rio Hondo Students was 12 beats per minute (bpm). The actual sample data is below. 61, 63, 64, 65, 65, 67, 71, 72, 73, 74, 75, 77, 79, 80, 81, 82, 83, 83, 84, 85, 86, 86, 89, 95, 95 Based on this sample, is there enough evidence to say that the standard deviation of the resting heart rates for students in this class is different from 12 bpm? Use =0.05=0.05. The null and alternative hypothesis would be: H0:2=9H0:2=9 H1:29H1:29 H0:=77.4H0:=77.4 H1:<77.4H1:<77.4 H0:p=0.48H0:p=0.48 H1:p0.48H1:p0.48 H0:=12H0:=12 H1:>12H1:>12 H0:=12H0:=12 H1:12H1:12 The test is: left-tailed right-tailed two-tailed Based on a sample of 25 games, The test statistic is: (to 3 decimals) The p-value is: (to 3 decimals) Based on both the p-value method and the classical method, we:

• Reject the null hypothesis
• Fail to reject the null hypothesis
