A dataset {5,10,15,20,25}\{5, 10, 15, 20, 25\}{5,10,15,20,25} is transformed by multiplying each value by 4, then adding 20. Which of the following statements about the transformed data MUST be true?

(1) New mean = 4×50+20=2204 \times 50 + 20 = 2204×50+20=220 (2) New median = 4×15+20=804 \times 15 + 20 = 804×15+20=80 (3) New variance = 42×50=8004^2 \times 50 = 80042×50=800 (4) New standard deviation = 4×504 \times \sqrt{50}4×50​
