Quizplus · Accepted Answer

To find the chi-square value for a one-tailed test with a significance level of 0.1 and sample size of 15, we need to look up the value in a chi-square table with 1 degree of freedom (df = n-1). The closest value to 0.1 in the table is 0.158 (the area to the left of the critical value), which corresponds to a chi-square value of 2.602. However, since this is a one-tailed test with the lower tail, we only need to consider the area to the left of the critical value (i.e., 0.1), which corresponds to a chi-square value of 7.78453. Therefore, the best choice is C.
