A study reported that 6% of the respondents were “Omnivores” who are gadget lovers, text messengers, and online gamers (often with their own blogs or Web pages), video makers, and YouTube posters. Suppose you believe that the percentage of students at the school who are Omnivores is greater than 6% and you plan to carry out a study to prove that this is so. You select a sample of 250 students and find that 23 can be classified as Omnivores. a. State the null and alternative hypotheses. b. Use either the critical value hypothesis-testing approach or the p-value approach to determine at the 0.05 level of significance whether there is evidence that the percentage of Omnivores at the school is greater than 6%.
