Answer:
46.08 students said that chicken is their favorite food.
Step-by-step explanation:
Let <em>X </em>denote the number of students who liked chicken.
The proportion of students who liked chicken is, <em>p</em> = 0.08.
About <em>n</em> = 576 students were surveyed about their favorite food.
Every student's answer was independent of the others.
Thus, the random variable <em>X</em> follows a binomial distribution with parameters <em>n</em> = 576 and <em>p</em> = 0.08.
The probability mass function of <em>X</em> is:
![P(X=x)={576\choose x}(0.08)^{x}(1-0.08)^{576-x};\ x=0,1,2,3...576](https://tex.z-dn.net/?f=P%28X%3Dx%29%3D%7B576%5Cchoose%20x%7D%280.08%29%5E%7Bx%7D%281-0.08%29%5E%7B576-x%7D%3B%5C%20x%3D0%2C1%2C2%2C3...576)
Then expected number of students who said that chicken is their favorite food is:
![E(X)=np\\\\=576\times0.08\\\\=46.08](https://tex.z-dn.net/?f=E%28X%29%3Dnp%5C%5C%5C%5C%3D576%5Ctimes0.08%5C%5C%5C%5C%3D46.08)
Thus, 46.08 students said that chicken is their favorite food.
304 pounds because 24% of 400 is 96 so you have to subtract 96 from 400
