Correct answer: I only- A. The medians for the two classes are the same.
- B. The lower extreme of Class B is greater than the lower extreme of Class A
- C. Class B has a smaller range of scores in the upper quartile than Class A.
- D. Class A performed better than Class B.
Explanation: Answer: D. The medians for the two classes are the same.. Explanation: Step 1: Calculate the median for each class.
Correct answer: The medians for the two classes are the same.- A. 32 °C
- B. 38.2 °CStart by taking the number in Fahrenheit and subtracting 32. Then divide the number by 9, and then multiply it by 5. This is how you convert Fahrenheit to Celsius or use the equation C = (F - 32) Ã- 5/9In this case, the answer is about 38.167 degrees Celsius.
- C. 36.5°C
- D. 213.3°C
Explanation: Start by taking the number in Fahrenheit and subtracting 32. Then divide the number by 9, and then multiply it by 5.
