A student wants to determine if there is a difference in the pricing between two stores for health and beauty supplies. She recorded prices from both stores for each of 10 different products Assuming that the conditions for conducting the test are satisfied, determine if there is a price difference between the two stores.

(c) Use technology to calculate the P-value
Round to three decimal places as needed.)
Transcribed Image Text:(d) Draw a conclusion based on the hypothesis test. Choose the correct answer below.
OA. There is not sufficient evidence to reject the null hypothesis because the P-value < x.
OB. There is not sufficient evidence to reject the null hypothesis because the P-value > a..
OC. There is sufficient evidence to reject the null hypothesis because the P-value <a.
OD. There is sufficient evidence to reject the null hypothesis because the P-value > α.
