Question

V. Sample size is n 25 alternative hypothesis is two-sided: nt E h. VI. Sample size is n 225 alternative hypothesis is two-sided: W. Comment: This is not an easy exercise, but don't let the surface mess of the picture put you off. The purpose of the exercise is to challenge you to think hard about very important issues in a new way and at the same time to challenge you to become more skillful at connecting graphs with ideas. We hope you won't give up and that you'll feel that what you learn from the time you spend is worth it. 1.0 0.8 0.6 0.4 0.2 -0.2 0.0 0.1 0.2 -0.1 Distance A. D. B. E. Extra credit: up to 1.5 points) Explain why you paired each curve with its respective description

Explanation / Answer

A. 2, The test is right sided and this curve has a tail to the right, also the variance is the least out of the 2 right sided graphs as this has higher sample size.
B. 4, The test is left sided and this curve has a tail to the left, also the variance is the least out of the 2 left sided graphs as this has higher sample size.
C. 3,The test is left sided and this curve has a tail to the left, also the variance is the most out of the 2 left sided graphs as this has lower sample size.
D. 1, The test is right sided and this curve has a tail to the right, also the variance is the most out of the 2 right sided graphs as this has lower sample size.
E. V, The test is two sided and this curve has a normal distribution or symmetrical distribution. Also the variance is the most out of the 2 symmetrical graphs as this has lower sample size.
F. VI, The test is two sided and this curve has a normal distribution or symmetrical distribution. Also the variance is the least out of the 2 symmetrical graphs as this has higher sample size.
