ONE-SAMPLE T-TEST
Production line for  filling up 1 litre bottles is set up such that themean value of volume should be
 500 ml. The quality control of 50 full bottles has revealed tha the average volume
of the liquid in a bottle was 497 ml with the standard deviation 5 ml. Is the production line set up correctly? 
"Test for the 0,05 significance level, expect normal population distribution. "

TWO-SAMPLE T-TEST …equal variances 		
"In a sport center there are two running paths Y and Z,  seemingly with the same length. An athlete has run"		
6-times path Y and 5 times path Z; measured times in seconds are given in a table. 		
"Test at the 0,05 significance level that the running time of the path Y is the same as the one of the path Z."		
Expect that the variance for both cases are the same.
