Use the following results obtained from a simple linear regression analysis with 12 observations.Y ^ = 37.2895 - (1.2024)XR2 = 0.6744 sb1 = 0.2934
Interpret the Regression equation results including the intercept, slope and the Coefficient of Determination. Test to determine if there is a significant negative relationship between the independent and dependent variable at = 0.05 and 0.01 (state whether it is one-tailed or two-tailed test). Also predict Y when X equals 10 units.
Find the values of the correlation coefficient and the coefficient of determination. Find the slope, y-intercept, and equation of the regression line for the data. Plot the points and a graph of the regression line on the same axes.
Consider a random variable Y, and a constant theta such that (1/theta)Y is distributed exponentially. Derive the lower and upper bounds for a 90% confidence interval for theta (These will be a function of y). Noe that theta=1/lambda where lambda i..
