Is this an of descriptive or inferential statistics? Select the correct choice below and fill in the answer box to complete your c O A. %; inferential OB. %; descriptive (f) Contact a local hospital and ask them the percentage of the population that is blood type O. Why might the results differ? O A. The results might differ because the results from the study are not likely to be similar to actual patients. O B. The results might differ because there is always variability because the individuals in a survey may not exactly reflect the makeup of the population. O C. The results might differ because certain hospitals only treat patients if they have blood type O. (g) Draw a frequency bar graph. Choose the correct answer below.
