A group of statistics students decided to conduct a survey at their university to find the average (mean) amount of time students spend studying per week. Based on a simple random sample, they surveyed 45 students. The survey showed that students studied an average of 18 hours per week with a standard deviation of 8 hours.

  • A national study found that students studied, on average, 15.0 hours.
  • You hypothesize that students at this university study more than the national average.
  • What is your alternate hypothesis? (Assume x represents the University students, and μ is the nation-wide average)
  • What is your null hypothesis? (Assume x represents the University students, and μ is the nation-wide average)
  • What is the standard error of the mean?
  • At a 95% confidence level (alpha = 0.05) what is the critical value?
  • What is your calculated t/z score?
