It was claimed that 65% of all dentists recommended a certain brand of gum for their gum-chewing patients. A consumer group doubted this claim and decided to test Ho:P =0.65 against the alternative Ha:P <0.65 where P is the proportion of the dentist who recommends the brand of gum. A survey of 390 dentists found that 273 recommended the given brand of gum. a) test the above-given hypothesis at alpha = 5%. Make sure to report test statistics and p-value of the test. b) What is your conclusion? Make sure to write the conclusion in context.
