The flu shot for a flu season is created from four strains of the flu virus, named Strain A, B, C, and D, respectively. Medical researchers use the following data to determine the effectiveness of the vaccine over the flu season. Table 1 shows the effectiveness of the vaccine against each of these strains individually. The graph below the table shows the prevalence of each of these strains during each month of the flu season, represented as a percentage of the overall cases of flu that month.

The Federal Bureau of Investigation (FBI) compiles data on crimes and crime rates and publishes the information in Crime in the United States. A violent crime is classified by the FBI as murder, forcible rape, robbery, or aggravated assault. The first two columns of Data set 1 give a relative-frequency distribution for (reported) violent crimes in the year 2010. A random sample of 500 violent-crime reports from last year yielded the frequency distribution shown in the first and third columns of Data set 1. At the 5% significance level, do the data provide sufficient evidence to conclude that last year's violent-crime distribution is different from the 2010 distribution? Use this information to answer the question. Click here to view the StatCrunch report. The value of the p-value is . Since the p-value distribution. (Round to four decimal places as needed.) α, we and determine that there sufficient evidence to conclude that last year's violent-crime distribution is different from the…
