Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate for the data below. College rankings Choose the correct answer below. A. The ordinal level of measurement is most appropriate because the data can be ordered, but differences cannot be found or are meaningless. B. The ratio level of measurement is most appropriate because the data can be ordered, differences (obtained by subtraction) can be found and are meaningful, and there is a natural starting point. C. The nominal level of measurement is most appropriate because the data cannot be ordered. D. The interval level of measurement is most appropriate because the data can be ordered, differences (obtained by subtraction) can be found and are meaningful, and there is no natural starting point. The data show the chest size and weight of several bears. Find the regression equation, letting chest size be the independent (x) variable. Then find the best predicted weight of a bear with a chest size of 48 inches. Is the result close to the actual weight of 528 pounds? Use a significance level of 0.05.

To determine her blood pressure, Samantha divides up her day into three parts: morning, afternoon, and evening. She then measures her blood pressure at 4 randomly selected times during each part of the day. What type of sampling is used? Stratified Random Convenience Cluster Systematic Time Remaining: 01:40:25 Next State whether the data described below are discrete or continuous, and explain why. The numbers of birds in different regions Choose the correct answer below. A. The data are discrete because the data can only take on specific values. B. The data are continuous because the data can take on any value in an interval. C. The data are discrete because the data can take on any value in an interval. D. The data are continuous because the data can only take on specific values. Time Remaining: 01:40:06 Next
