Answer with explanation:</h2>
Let p be the proportion of the correct answers.
As per given , we have

, since the alternative hypothesis is right tailed , so the test is a one -tailed test.
If the student gets 52 answers correct out of 80.
i.e. the proportion of correct answers : 
Test statistic : 

P-value :
[ by using p-value table for z (right-tailed)]
Since the p-value(0.0037) is less than the significance level (0.05), so we reject the null hypothesis.
Results : We have enough evidence to support the claim that a student knows more than half of the answers and is not just guessing.
You didn’t give answer choices, so I would say it would probably be;
50/x Or some other variable.
If you aren’t clear on what a variable is, it’s a letter that represents an unknown factor or numerical value in an expression.
If you aren’t aware of what 50 is divided by, my guess is you’d use a variable to state this.
So your answer should be 50/*variable*
In my example I used x, but your answer might use another letter.
I hope this helps, and I’m sorry if I’m wrong.
Good luck. :))
