In a survey of 120 randomly selected A&T students 72 stated the William\'s Cafe food was good or better than good. Use the sample data with a .05 significance level to test the claim that most (more than 50%) of the A&T students feel the food is good or better than good.

Answer the following:

The original claim is that the students feel the food rates better than what proportion?

What is the value of the np test? (Hint: That is what is n times p)

What is the value of the nq test?

Do these pass the 5 or more rule? (yes or no)

What is p-hat?

What is p?

What is q?

What is Ho? ( p=, p>, or p<)

What is H1? (p=, p>, or p<)

Compute the test statistic?

Give the critical value?

Do you reject the null or fail to reject the null?

Can you conclude that the A&T students rate the food good or better than good more than 50% of the time?
