- A grocer finds that the cantaloupes in his store have weights with mean 0.7 kg and standard deviation 53 grams. If this is true, then 99.7% of cantaloupes will have weights between how many grams?A soda company claims that the mean amount of soda in their bottles is 12 ounces. Determine whether the hypothesis for this claim is left-tailed, right-tailed, or two- tailed. two-tailed right-tailed left-tailedA company audit reveals that 3% of the department budgets contain errors. A program is developed to analyze budgets and, in a test, identifies errors in 99% of budgets with errors and 2% of those without. If a budget is identified by the program as possibly having an error, what is the probability that the budget does have an error? (Hint: Use the tree diagram, check out the examples in the Bayes' theorem notes)
