Please complete the following questions with detailed steps and explanations. Historically, 15% of students at a university undertake an internship during the summer break. A university claims that the number of students who took up summer internships reached a record high in 2015. A sample of 400 students reveals that 120 were working as interns in the summer of 2015. Use a 1% significance level to determine if there is any evidence that the proportion of students in internship positions...
