Relative Frequency distribution for Violent crimes in 2010
Murder. 1.1%
Forcible Rape 6.3%
Robbery 28.6%
Aggravated Assault. 64%
To compare the distribution of crimes between the year 2010 and 2020, a sample of 500 violent crimes were randomly selected:
Murder 3
Forcible Rape 37
Robbery 154
Aggravated Assault. 306
Perform a hypothesis test at the 5% significance level to determine if the distribution of violent crimes in 2020 has changed from the distribution in 2010.
1) State null and alternative hypothesis
2) Find Test Statistics
3) Find the p-value
4) Conclusion
