A major credit card company is investigating whether the distribution of the number of credit cards used by its customers has changed from last year to this year. Customers are classified as using 1 card, 2 cards, or more than 2 cards. The company conducts a chi-square goodness-of-fit test to investigate whether there is a change in the distribution of number of cards used from last year to this year. The value of the chi-square test statistic was χ2=7.82χ2=7.82 with a corresponding pp-value of 0.02. Assuming the conditions for inference were met, which of the following is the correct interpretation of this pp-value?
Comfort Food Magazine states the average calories of a medium size hot dog is 209. The number of calories for a medium size hot dog is normally distributed. A random sample of 15 different brands of medium size hot dogs resulted in the following calorie count provided below.

The manufacturer of a new eye cream claims that the cream reduces the appearance of fine lines and wrinkles after just 1414 days of application. To test the claim, 1010 women are randomly selected to participate in a study. The number of fine lines and wrinkles that are visible around each participant’s eyes is recorded before and after the 1414 days of treatment. The following table displays the results. Test the claim at the 0.050.05 level of significance assuming that the population distribution of the paired differences is approximately normal. Let women before the treatment be Population 1 and let women after the treatment be Population 2.
