1 Nine out of ten dentists recommend this toothpaste! You have certainly heard the above claim before. Advertisers frequently claim that some percentage of doctors or dentists recommend a given health product. It's best to take such claims with a large grain of salt. Suppose a recent advertisement claims that 9 out of 10 dentists (90%) recommend a certain brand of toothpaste. A consumer advocacy group is highly suspiciour of this claim and randomly surveys 209 dentists. They find that 83.8% of the sample recommends the given brand of toothpaste. Using a = 0.01, test the hypothesis that the proportion of all dentists who recommend this brand of toothpaste is different than 90%.
