A behavioral neuroscientist measures the amount of thyroid hormone in a sample of female mice because she believes the hormone level will correlate with the animals' maze learning ability. The scientist will later test the learning performance using a maze solving task. The thyroid hormone data are displayed in the frequency distribution table below. Answer the following question using the thyroid hormone data. X (mg/ P dl) 10 - 19 3 0.09 20 - 29 2 0.06 30 - 39 7 0.22 40 - 49 12 0.38 50 - 59 6 0.19 60 - 69 2 0.06 If the scientist randomly chooses a mouse from this sample, what is the probability that she chooses a mouse with a thyroid hormone level less than 40 mg/ dl? O p =0.19 O p = 0.37 O p = 0.22 O p =0.63
