Chapter 17, Problem 5PS

A hotel has designed a new system for room service delivery of breakfast that allows the customer to select a specific delivery time. The file Satisfaction contains the difference between the actual and requested delivery times (a negative time means that the breakfast was delivered before the requested time) recorded for 30 deliveries on a particular day along with whether the customer had previously stayed at the hotel.

a. Using all the data as the training sample, develop a classification tree model to predict the probability that the customer will be satisfied based on the delivery time difference and whether the customer had previously stayed at the hotel.

b. What conclusions can you reach about the probability that the customer will be satisfied?

explain the importance of the Hypothesis test in a business setting, and give an example of a situation where it is helpful in business decision making.
A college wants to estimate what students typically spend on textbooks. A report fromthe college bookstore observes that textbooks range in price from $22 to $186. Toobtain a 95% confidence level for a confidence interval estimate to plus or minus $10,how many students should the college survey? (We may estimate the populationstandard deviation as (range) ÷ 4.)
In a study of how students give directions, forty volunteers were given the task ofexplaining to another person how to reach a destination. Researchers measured thefollowing five aspects of the subjects’ direction-giving behavior:• whether a map was available or if directions were given from memory without a map,• the gender of the direction-giver,• the distances given as part of the directions,• the number of times directions such as “north” or “left” were used,• the frequency of errors in directions. Identify each of the variables in this study, and whether each is quantitative orqualitative. For each quantitative variable, state whether it is discrete or continuous. Was this an observational study or an experimental study? Explain your answer.
