The quality of the orange juice produced by a manufacturer is constantly monitored, There are numerous sensory and chemical components that combine to make the best-tasting orange juice, For example, one manufacturer has developed a quantitative index of the "sweetness" of orange juice. Suppose a manufacturer wants to use simple linear regression to predict the sweetness (y) from the amount of pectin (x). Find a 90% confidence interval for the true slope of the line. Interpret the result. E Click the icon to View the data collected on these two variables during 24 production runs at a juicemanufacturing plant. Data table E) A 90% confidence interval for the true slope of the line is (l , ). Run Sweetness Index Pectin (PP'T'l (Round to four decimal places as needed.) 5'2 220 5.5 227 Choose the correct answer below. 6.0 256 Q A. We are 90% confident that the change in the mean sweetness index for each one unit change in the pectin is not between the limits of the confidence interval. 5-9 210 . 5.8 224 B We are 90% confident that the change in the mean sweetness index for each one unit change in the pectin is between the limits of the confidence interval. 6 0 215 C. We are 10% confident that the change in the mean sweetness index for each one unit change in the pectin is between the limits of the confidence intewal. 53 233 5.6 267 5.6 239 5.9 212 5,4 410 5.6 254 5.8 307 5.5 259 5,3 284 5.3 383 5.7 271 5.5 264 5.7 227 5,3 263 5.9 231 5.8 220 5.8 246 5.9 241
