II. For each of the following experiments you should identify the variable(s) in the study, the data type of each variable, and the sample size. 1. For each of 10 beetles, a biologist counted the number of times the beetle fed on a disease-resistant plant during a 4-hour period. 2. In a nutritional study, 40 healthy males were measured for weight and height as well as the weight of their food intake over a 24-hour period. 3. Seven horses were included in a 2-week study. After the first week a veterinarian measured the heart rate of each of the horses after an identification chip was inserted in its neck. At the end of the second week the veterinarian again measured the heart rate after branding the horses with a hot iron. 4. The birth weight, number of siblings, mother's race, and mother's age were recorded for each of 85 babies. Solution: No. variables data type sample size 1 3 4
