2. [5 Points] It was claimed that 75% of all dentists recommend a certain brand of gum for their gum-chewing patients. A consumer group doubted this claim and decided to test H_0:p=0.75 against H_a:p<0.75, where p is the proportion of dentists who recommend that brand of gum. A survey of 390 dentists found that 273 recommended the given brand of gum. At the 5% significance level, do the data provide sufficient evidence to conclude that the proportion p is less than 0.75? You have to include Minitab output and use the P-value in Minitab output.
