Question
Student use of cell phones during class is perceived by many faculty to be an annoying but perhaps harmless distraction. However, the use of a phone to text during an exam is a serious breach of conduct. The article "The Use and Abuse of Cell Phones and Text Messaging During Class: A Survey of College Students" (College Teaching, 2012: 1-9) reported that 27 of the 267 students in a sample admitted to doing this. Can it be concluded at significance level .001 that more than 5% of all students in the population sampled had texted during an exam? State the null and alternative hypothesis. Calculate test statistics What is the critical value? Do you reject or fail to reject the null hypothesis? What is your conclusion? How would you calculate p-value in a computing language? Use either R, Python, or Matlab.
