    Samantha is studying different species of irises. During her fieldwork, she recorded the length of the sepal in millimeters of two different species, I. setosa and I. virginica. She wants to know if the two species differ in sepal length or not. Using the software tool you prefer, perform a two-sample t-test for the difference between means to decide whether the two species of irises have different sepal lengths. You may find this list of software manuals helpful in computing...

    Sylvia, a manager of a pizzeria wants to optimize the average delivery time of orders from the current 35 minutes. To do this, Sylvia overhauls the delivery ordering system and rejigs the delivery routes. After all the changes are implemented, she takes a random sample of 30 delivery orders and yields an average delivery time of 32 minutes. The population standard deviation is known to be 6 minutes. Were these changes successful in reducing the average delivery time of pizza?...

    Walzon recently made changes to its inventory management and delivery systems. Walzon wants to know whether these changes have reduced mean delivery time (number of hours from placing an order to receiving the item). Walzon wants to test the null hypothesis that mean delivery time is at least 37 hours against the alternative hypothesis that mean delivery time is less than 37 hours. Assume that delivery times are approximately normally distributed, with a known standard deviation of 8 hours. A...
