Are avid readers more likely to wear glasses than those who read less frequently? Three hundred men in Ohio were selected at rande and characterized as to whether they wore glasses and whether the amount of reading they did was above average, average, or below average. The results are presented in the following table: Amount of Glasses reading Yes No Above 47 26 average Average 48 78 Below 31 70 average Total 126 174 Suppose we wish to test the null hypothesis that there is no association between the amount of reading and wearing glasses. Under the mull hypothesis, what is the numerical value of the chi-square statistic?
