Question: A recent marketing and promotion campaign by Charles of the Ritz more than doubled the sales of the suntan lotion Bain de Soleil, which has become the nation's number 2 suntan product. At the end of the promotional campaign, the company wanted to test the hypothesis that the market share of its product was 0.35 versus the alternative hypothesis that the market share was higher than 0.35. The company polled a random sample of bathers on beaches from Maine to California and Hawaii, and found that out of the sample of 3,850 users of suntan lotions, 1,367 were users of Bain de Soleil. Do you reject the null hypothesis? What is the p-value? Explain your conclusion.
