Question

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 αα = 0.05 to test to see if a crew-member's fatality onscreen is dependent on their uniform color.

	Alive	Dead	Total
Blue	42	11	53
Gold	19	6	25
Red	29	25	54
Total	90	42	132

Choose the correct null and alternative hypotheses.
- H0:H0: There is an association between Star Trek fatalities and uniform color.
  HaHa There is no association between Star Trek fatalities and uniform color.
- H0:H0: There is no association between Star Trek fatalities and uniform color.
  HaHa There is an association between Star Trek fatalities and uniform color.
Compute the test statistic.

Complete the following table of expected counts. (Round your answers to 4 decimal places).

Alive Dead

Blue

Gold

Red

Compute the value of the test statistic. (Round your answer to 4 decimal places.)

χ2=χ2=
Compute the p-value. (Round your answer to 4 decimal places.)

pp-value =
Interpret the results of the significance test.
- The p-value provides strong evidence against the null hypothesis. The association between Star Trek fatalities and uniform color is statistically significant.
- The p-value provides little evidence against the null hypothesis. The association between Star Trek fatalities and uniform color is not statistically significant.
