The Technology Operation Department wants to determine if the proportion of students who have personal computers at home is different from the national proportion of 30%. A random sample of 400 students were sampled, and 104 have a p.c. at home. (Hint: This is a proportion problem). Which of the following are the null and alternative hypotheses? (Hint: Is this two-side test or not?)

And then it gave me 4 options which I'll type out now.
