Please write clearly because words and numbers that cannot be read without difficulty will count as not written. Please submit only one assignment per team. For each question provide: a) A justification of the statistical test you selected. A reference to a one-tailed or a two-tailed test does not answer adequately to this question (0.5 points) b) The statistical hypotheses (null and alternative hypotheses). The mathematical no- tation is not accepted (0.5 points) 0) The calculations and the results of the statistical test (1.5 points) d) Your interpretation of the results of the statistical test. Specify if you accept or you reject the null hypothesis and give the practical implications. The level of significance (or) is 5% (or 0.05). (0.5 points) Each question is worth 3 points for a total of 6 points. The teaching assistant and course instructor do not provide help on the theory of the course.
