A survey was recently conducted in which males and females were asked whether they owned a laptop personal computer.The following data were observed:

Given this information,if an alpha level of .05 is used,the critical value for testing whether the two variables are independent is x² = 3.8415.

Quizplus · Accepted Answer

In order to verify whether the critical value given is correct or not, we need to conduct a chi-square test of independence using the observed frequencies. However, the observed frequencies are not provided in the given data. Therefore, we cannot verify the accuracy of the critical value. However, assuming that the critical value is correct, the answer would be A as it suggests that the null hypothesis of independence should be rejected if the test statistic is greater than 3.8415 at alpha level .05.
