Problem 17
Still rockin Crowd Management Strategies monitors accidents at rock concerts. In their database, they list the names and other variables of victims whose deaths were attributed to crowd crush at rock concerts. Here are the histograms and boxplot of the victims ages for the data from 1999 to 2000: 12 22 32 42 Age (yr) 5 10 15 20 25 # of Deaths 10 20 30 40 50 Age (yr) a) What features of the distribution can you see in both the histogram and the boxplot? b) What features of the distribution can you see in the histogram that you could not see in the boxplot? c) What summary statistic would you choose to summarize the center of this distribution? Why? d) What summary statistic would you choose to summarize the spread of this distribution? Why?

Step-by-Step Solution:
Step 1 of 3
Inference for two independent groups: - This means deciding if there’s a statistically significant relationship between explanatory and response variable - If response variable is quantitative, the question involves means o Ex. How does average childhood weight compare between generations - If the response variable is categorical, the question involves proportions o Ex. Does the smoking rate differ between genders Summary of inference for 2 independent population means: - Hypotheses: H 0μ 1μ =2 H A μ1−μ 2¿0 - Sample Statistic: ´ ´ X 1X 2
