can someone fill in the blanks

Keep the Highest: /8 Attempts: Aa Aa 5. Hypothesis test about two population means, population standard deviations unknown Most consumers are not diamond experts, so many rely on an independent certification body to determine a diamond's value Diamonds are assessed on four characteristics, referred to as the "four Cs": carat weight, color, clarity, and cut. Several certification bodies issue diamond grading reports, including the Gemological Institute of America (GIA), the Hoge Raad voor Diamant (HRD), and the International Gemological Institute (IGI), If a certification body is recognized as being strict in its grading, diamonds certified by that body may sell for higher prices than diamonds with the same grades that are certified by a different body. In this problem, compare the prices of diamonds graded by one certifier to the prices of diamonds graded by a different certifier to learn whether one population carries a price premium The Diamonds dataset in the Dataview tool below contains data on the carat weight, color, clarity, certification body, and selling price of a random sample of 308 round-cut diamond stones.
