I was given the following exercise:
The Results obtained by 10 students in a test are the following:
72 95 79 83 93 80 91 74 70 86
Test the hypothesis that the mean score is 75.Use two test:one parametric and another non-parametric.
My doubt is for the parametric test, should I make a t-student test? Because I don't have a big sample to use the normal distribution...
