What isdifference between a repeated measures study and a matched pairs study?a. A repeated measures study is analyzed with related sample and t-test while a matchedpairs study is analyzed with an independent sample t-testb. A repeated measures study tests one group while a matched pairs study tests two groupsA matched pairs study needs fewer participants than a repeated measures study to havethe same statical powerс.d. They are not different they are synonyms for the same type of study design

The height of a triangle is measured as 26.2 cm, with the base measured as 17.4 cm. The measurement of the height can be off by as much as 0.8 cm, and that of the base by no more than 1.2 cm. Estimate the maximum possible error in calculating the area of the triangle. ... Thus, the maximum possible error in calculating the area of the triangle is approximately cm².
