Doug believed that weather forecasteres always predicted temperatures higher than what actually happened because people like warmer temperatures. He obtained a sample mean as 0.8 degrees. His hypothesis were Ho: mean=0 degrees and Ha:mean > 0 d
If the tube elongates 3mm and its circumfrence decreases 0.09 mm, determine the modulus of elasticity, Poisson's ratio, and the shear modulus of the tube's material. The material behaves elastically.
If you had the chance to set up a simple experiment at your workplace to test a hypothesis, would you have your research design focus on group comparison (e.g., t-test), pre-post change (e.g., paired t-test), or correlation between variables (e.g.
