A phlebotomist draws the blood of a random sample of 50 patients and determines their blood types as shown: (a) Construct a frequency distribution. (b) Construct a relative frequency distribution. (c) According to the data, which blood type is most common? (d) According to the data, which blood type is least common? (e) Use the results of the sample to conjecture the percentage of the population that has type O blood. Is this an example of descriptive or inferential statistics? (f) Contact a loc
