What type of statistical test that could used to test the following hypothesis. (A) there are 92 public colleges and universites in Canada. The average tution in 2016-2017 was $6392 per year(2 semesters) You believe that the tution has increase signifcantly for 2016-2017 school year. You sample the published tution fee for 12 schools across Canada . You find the mean tution fee for the same period is $6879 with a standard deviation of $568.
