Macmillan Learning Male Drosophila become sterile when exposed to moderately high temperatures because sperm is damaged by heat at much lower temperatures than other cells. Rohmer et al. (2004) asked whether flies from warmer climates are adapted to higher temperatures. They collected flies from France (where it is relatively cool) and India (relatively warm) to test the effects of temperature on sterility. In one procedure, they raised male flies from both locations at a high temperature, 30.5° C, and recorded whether the flies were sterile or fertile. Thirty-two out of 50 flies from France were sterile at this temperature, whereas 20 of 50 flies from India were sterile. Is there evidence that the populations of flies from these two locations differ in their frequency of sterility at this temperature? To answer this question, you should perform the x² contingency test. Use the level of significance a = 0.05 for the test and use Statistical Table A when determining the statistical significance. Calculate the x² test statistic. Give your answer to two decimal places. Avoid rounding within calculations.

Male Drosophila become sterile when exposed to moderately high temperatures because sperm is damaged by heat at much
lower temperatures than other cells. Rohmer et al. (2004) asked whether flies from warmer climates are adapted to higher
temperatures. They collected flies from France (where it is relatively cool) and India (relatively warm) to test the effects of
temperature on sterility. In one procedure, they raised male flies from both locations a high temperature, 30.5° C, and
recorded whether the flies were sterile or fertile. Thirty-two out of 50 flies from France were sterile at this temperature,
whereas 20 of 50 flies from India were sterile.
Is there evidence that the populations of flies from these two locations differ in their frequency of sterility at this temperature?
