Do low sodium hot dogs really live up to their name? A consumer watchdog organization tested 45 randomly chosen "reduced sodium" hot dogs, finding an average sodium content of 332 mg with a standard deviation of 36 mg. A histogram of these sodium values shows a left-skewed shape. (a) The data analyst in charge of this project is worried about the left-skewed shape. Is it valid to construct a confidence interval in spite of the skewness? O No Yes (b) Construct a 99% confidence interval for the average sodium content for these type of hot dogs. (Use 4 decimal places.) ( (c) How should this interval be interpreted? O We are 99% confident that a randomly chosen hot dog of this type will have a sodium content that falls inside the above interval. We are 99% confidence that all hot dogs of this type have a sodium content that falls inside the above interval. We are 99% confident the above interval contains the average sodium content for the hot dogs in this particular sample. O We are 99% confident the above interval contains the average sodium content for all hot dogs of this type.
