Her null hypothesis is that a student will get 50% of the questions on the exam correct. The alternative hypothesis is that the student is not guessing and should get more than 50% in the long run. H,p=0.50 H:p> 0.50 A student gets 30 out of 50 questions or 60% correct. The p-value is 0.079. Explain the meaning of the p-value in the context of this question.
