The sample data table Hot Dogs.jmp came from an investigation of the taste and nutritional content of hot dogs.

(a) Construct a histogram of the type of hot dogs (beef, meat, and poultry). Is there an equal number of each type considered?

(b) The $/oz variable represents the cost per ounce of hot dog. Construct an outlier box plot of this variable and find any outliers.

(c) Construct a 95% confidence interval for the caloric content of the three types of hot dogs. Which type gives (on average) the lowest calories?

(d) Test the conjecture that the mean sodium content of all hot dogs is 410 grams.
