Students conducted a survey and found out that 36% of their peers on campus had tattoos, but only 4% of their peers were smokers. if 100 students were surveyed, can these students use the normal approximation to study the proportion of students in the population who have tattoos?

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
