... 4. P-value: Since we perform a lower tail test the P-value = P (t < t0 ) = P (t > abs(t0 )). Use table IV from the text book. Focus on row with df = 7, observe that abs(t0 ) = 4.65 is larger than the largest the value in this row, 3.499. Here: 3.499< 4.65. Then the P-value is smaller than the upper ...

This generalization is based on a distribution of sample means for all possible random samples. This distribution is called a Sampling Distribution. It d ...
