5.85 Set up a contingency table for the appropriate variables, then determine the following probabilities:

a. [variables 4 and 26] Given that the random respondent is a female, what is the probability that she spends at least $15 during a trip to Springdale Mall? Is a male more likely or less likely than a female to spend at least $15 during a visit to this area?

b. [variables 5 and 26] Given that the random respondent is a female, what is the probability that she spends at least $15 during a trip to Downtown? Is a male more likely or less likely than a female to spend at least $15 during a visit to this area?

c. [variables 6 and 26] Given that the random respondent is a female, what is the probability that she spends at least $15 during a trip to West Mall?

Is a male more likely or less likely than a female to spend at least $15 during a visit to this area?

Based on the preceding probabilities, at which shopping areas are males and females most likely and least likely to spend $15 or more during a shopping visit?
