Use appropriate technology to compute the value of the test statistic (rounded to 2 decimal places) and the P-value (rounded to 3 decimal places). x²2: P-value = d. Interpret the results of the significance test. The P-value provides little evidence against the null hypothesis. The association between Star Trek fatalities and uniform color is not statistically significant. The P-value provides strong evidence against the null hypothesis. The association between Star Trek fatalities and uniform color is statistically significant.

The color of the Star Trek uniform represents each crew-member's work area. In the original Star Trek
series, blue shirts are worn by medical and science staff, gold shirts are worn by the command division, and
the red shirts were worn by engineering, security and communications division. We will statistically assess
whether there is a connection between uniform color and the fatality rate. The table below shows a
sample of how many crew-members in each area have died onscreen and their shirt color. Use a = 0.05 to
test to see if a crew-member's fatality onscreen is dependent on their uniform color.
