To appreciate the impact of large sample size on the value of x2, multiply each of the observed frequencies in the previous question by 10 to obtain the following:
Even though the sample size has increased by a factor of 10, the proportion of males (and females) who favor gun control remains the same as in the previous question. In both questions, gun control is favored by .67 of all males (from 40/ 60 5 400/ 600 5 .67) and by .75 of all females (from 30/ 40 5 300/ 400 5 .75).
(a) Using the .05 level of significance, again test the null hypothesis for gender and attitude toward gun control.
(b) Specify the approximate p-value for this test result.
(c) Given a significant x2 for the current analysis, estimate the effect size.
