Identify the least squares point estimates 30 and 3₁. Identify SSE, s² and s. Identify p-value for testing Ho B₁0, Ha: ₁0. Using p-value, state the conclusion by setting a equal to .05. (What do you conclude about the relationship between y and x)? Calculate 95% and 99% confidence interval for ₁. Identify the p-value for testing Ho Bo=0, Ha: Bo 0. Using p-value, state the conclusion by setting a equal to .05. Report a point estimate of and a 95% confidence interval for the mean demand and predic- tion interval for the actual demand for Fresh in all sales periods when the price difference is 0.1. Find the total variation, the unexplained variation, the explained variation, the simple coefficient of determination (2). Also, interpret r².
