A student wishes to compare the cost of textbooks from two sellers. The same forty textbooks are priced at both seller A and seller B. Specifically, the student is determining whether at the 0.01 significance level there is sufficient evidence that the mean textbook cost from seller A is lower than the mean cost of textbooks from seller B. A computer is used and it is found that the P-value = 0.005. Which of the following statements is true?
A. This is a test regarding two dependent samples. There is sufficient evidence to conclude that the mean price of textbooks is lower at seller A.
B. This is a test regarding two dependent samples. There is insufficient evidence to conclude that the mean price of textbooks is lower at seller A.
C. This is a test regarding two independent samples. There is sufficient evidence to conclude that the mean price of textbooks is lower at seller A.
