Step by step
Solved in 3 steps
- In the regression modelY = β0 + β1X1 + β2X2 + εthe extent of any multi collinearity can be evaluated by finding the correlation between X1 and X2 in the sample. Explain why this is so.The foreman at a large plant estimates that there are defective parts about 1% of the time. If the plant produces 20,000 parts in a week, what is the variance for the number of defective parts?find the correlation coefficent using pearson's method
- An experiment is conducted to see the effect of light intensity on plant growth, what is the dependent variable in this scenario?After performing a statistical regression on a set of data the value of the correlation coefficient r was -0.2041. What does that imply about the data?A simple main effect test is appropriate for analyzing which significant result?
- The plot presents some results for a simple linear regression analysis between two variables. (IMG 1) Is it true to say that the linear correlation coefficient is 0.6839? this is true or false?Which graph used in a residual analysis provides roughly the same information as a scatterplot? What advantages does it have over a scatterplot?a sample of 60 grade 9 student age was obtained to estimate the mean age of all grade 9 students. x = 15.3 years and the population variance is 16
