A study was conducted to find out. A random sample of 20 individuals was chosen and each was presented a glass of the soft drink with a different sugar level (x, in grams). Each respondent was ask to provide a rating (y, in points) of the soft drink according to the following scale: 5 = excellent, 4 = good, 3 = average, 2 = fair, and 1 = poor. Is sugar content a significant cause of rating? Formally test a relevant hypothesis at the 0.01 level of significance. Will your 99% confidence interval for the true slope coefficient include zero (i.e., will the interval goes from negative to positive)? Explain carefully by drawing on result of the p-value in part (a), without constructing the confidence interval for the true slope coefficient. You will not get credit if you answer this question by constructing a confidence interval. Your grade depends on how well you explain and draw a conclusion from result of part (a). Construct the 95% confidence interval for the expected value (mean) of ratings for those presented a drink with a sugar content of 11. â€¢ Show less
