In random samples, 74 of 250 persons who watched a certain television program on a small TV set and 92 of 250 persons who watched the same program on a large set remembered 2 hours later what products were advertised. Use the x2 statistic to test the null hypothesis θ1 = θ2 against the alternative hypothesis θ1 ≠ θ2 at the 0.01 level of significance.
