Suppose that 9 of 100 Caucasian adolescent girls, 12 out of 95 African American adolescent girls, and 10 out of 90 Hispanic adolescent girls are above the 90th percentile for blood pressure.
Calculate the test statistic.(a) 30 (b) 2 (c) 1.14 (d) 0.566
For the previous test, report a two-tailed p-value.(a) 0.0283 (b) 0.717 (c) 0.434 (d) 0.566
