Problem 6
Marketing: Shopping Time How much customers buy is a direct result of how much time they spend in the store. A study of average shopping times in a large national houseware store gave the following information (Source: Why We Buy: The Science of Shopping by P. Underhill): Women with female companion: 8.3 min. Women with male companion: 4.5 min. Suppose you want to set up a statistical test to challenge the claim that a woman with a female friend spends an average of 8.3 minutes shopping in such a store. (a) What would you use for the null and alternate hypotheses if you believe the average shopping time is less than 8.3 minutes? Is this a right-tailed, left-tailed, or two-tailed test? (b) What would you use for the null and alternate hypotheses if you believe the average shopping time is different from 8.3 minutes? Is this a right-tailed, left-tailed, or two-tailed test? Stores that sell mainly to women should figure out a way to engage the interest of men! Perhaps comfortable seats and a big TV with sports programs. Suppose such an entertainment center was installed and you now wish to challenge the claim that a woman with a male friend spends only 4.5 minutes shopping in a houseware store. (c) What would you use for the null and alternate hypotheses if you believe the average shopping time is more than 4.5 minutes? Is this a right-tailed, lefttailed, or two-tailed test? (d) What would you use for the null and alternate hypotheses if you believe the average shopping time is different from 4.5 minutes? Is this a right-tailed, left-tailed, or two-tailed test?

Step-by-Step Solution:
Step 1 of 3
Parameter Population Proportion, a fixed quantity. Population Proportion = p Sample Proportion = p hat (estimate) number of successes over the sample size Will modify from each sample Only estimate of parameter Sampling Distribution of Statistics Values of the figure from all potential sample size Describing quantitative number Center mean of all values of the parameter Spread increasing of sample size means the spread is decreasing Shape sample size increases the graph looks more as a bellshaped Caveats Must have a symbolic tester N must be “big enough” Normal Distribution Draw curve and axis Area that signifies probability
