A governmental agency computed the proportion of violent crimes in the United States in a particular year falling into each of four categories. A simple random sample of 600 violent crimes committed in California during that year were categorized in the same way. The following table presents the results. Murder: US proportion is 0.01 CA frequency is 10, Forcible rape: US proportion is 0.05 CA frequency is 37, Robbery: US proportion is 0.360 CA frequency is 203, Aggravated assault: US proportions 0.580 CA frequency is 350. Can you conclude that the proportions of crimes in the various categories in California differ from those in the United States as a whole? Use the 0.025 level of significance and the p-value method with the TI-84 Plus calculator. State the null and alternate hypotheses.
