a) A political pollster reports that his candidate has a 10% lead in the polls with 10% undecided. Observation as he is only guessing as to the conclusion that will overcome the final analysis. Observation is the presence of observing only where the experimental is adding to or taking from. 5) Select the study that is most appropriate and EXPLAIN WHY it is most appropriate for the study. a) Is the aspirin produced by a particular pharmaceutical company better than that of a competitor at relieving headaches? Which of the following would best be used to study this: 1) a case-controlled observation; 2) an observation; 3) a double-blind experimental procedure; and 4) and experimental procedure. Using the double-blind experimental procedure would be the likely use as this would keep any and all researches out of the equation so the test would be completed without bias.

(Just divide 100 by 16)
c. Convert 0.45 to a percent Percentage: Move the decimal two places to the right..... 45%
Fraction: Put 45% over 100 and reduce it to its lower terms...... 9/20 d. Humanities majors spend an average of $115 per course on books. Mathematics majors spend an average of $70 per course on books. What is the percent difference between the two amounts relative to the amount for mathematics majors (round to the nearest percent)? The required percentage = ((115- 70)*100)/70 % = 64.29% e. Suppose that the cost of a statistics text was $50 in 1985 and is $100 in 2000. What is the “Statistics Text Index” number, rounded to the nearest tenth, for the 2000 edition with the 1985 price as the reference value? (100/50) x100 = 200%
