Statistics 2018/2019

Slides 9-11 of the block "Inference II" have to be replaced by these new ones.

Notice that I included a slightly modified Exercise on the T-test to compare 2 means, followed by the illustration of what changes in 2 slightly different scenarios. This exercise is used to introduce better the topic "ANOVA 1-way" (but the old exercise was correct anyway)

There is a copy-paste error in the TABLE of sample data of Scenario 3 (second slide on page 2): the observed means are 94 and 102 (not 98) as in Scenario 1; the calculation of the test statistics uses in fact 94 and 102 (thus, calculations are CORRECT)
