# Introduction to statistics

Based on the relative frequencies for responses to each variable, determine the probability that a randomly selected respondent from: a. [variable 4] spends at least $15 during a trip to Springdale Mall.

b. [variable 5] spends at least $15 during a trip to Downtown.

d. [variable 6] spends at least $15 during a trip to West Mall.

Comparing the preceding probabilities, which areas seem strongest and weakest in terms of the amount of money a shopper spends during a typical shopping visit?

e. [variable 11] feels that Springdale Mall has the highest-quality goods.

f. [variable 11] feels that Downtown has the highest-quality goods.

g. [variable 11] feels that West Mall has the highest-quality goods.

Comparing the preceding probabilities, which areas are strongest and weakest in terms of the quality of goods offered?

Set up a contingency table for the appropriate variables given, 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...
