A bottler of coconut water found that adults in the US consume, on average, 75 servings of coconut water in one year. The bottler suspects that adults in the US, who are of South East Asian origin, drink less than the national average because they have tasted the real thing and find the bottled coconut water to taste artificial. A sample of 50 South East Asians yielded a sample mean of 72 servings and a sample standard deviation of 11 servings. Construct a null and alternate hypothesis that the bottling company can use to confirm their suspicion. Based on the sample data, and a 2% level of significance, what can they conclude? What would your conclusion be at a 1% level of significance? [show excel function and inputs]
