Data on the amount of weight of carrots harvested per 1 km² area from fields in 130different farms is collected and stored in R in the vector y alongside data from each farm onfive possible explanatory variables x1 x2 x3 x4 x5. Every possible linear regressionmodel using these five explanatory variables without transformation is fitted along with thenull model.The ANOVA table for the full model with all 5 explanatory variables is given below.d.f.SS52801249681291248SourceRegressionResidualsTotalMS567.806VR7.174A reduced model using only variables x1 and x3 is also fitted with the same data(f) If the Regression Sum of Squares for this reduced model is 195, complete the ANOVAtable for this two-variable model.DrawingK

In a study of cars that may be considered classics (all built in the 1970s), the least-squares regression line of mileage (in miles per gallon) on vehicle weight (in thousands of pounds) is calculated to be mileage = 45 – 7.5 weightThe mileage for a small Chevy is predicted to be 22 miles per gallon. What was the weight (lbs) of this car? Please show work of calculations
A group of 13 healthy children and adolescents participated in a phycological study designed to analyze the relationship between age and average total sleep time (ATST). To obtain a measure for ATST (in minutes), recordings were taken on each subject on three consecutive nights and then averaged. Results are provided to you in Sleep&Age.xlsx Download Sleep&Age.xlsx file. (2 points) Determine the least-squares regression line for predicting average total sleep time using age. (2 points) Make a scatter plot of the data with ATST on the y-axis (vertical axis) and Age on the x-axis (horizontal axis) with least squares regression line overlaid on the top (i.e.: obtain the fitted line plot). Make sure to attach the plot below. (7 points) Check the assumptions for the simple linear regression. Attach any plots you used check the assumptions and comment on them. (7 points) We want to see if the average sleep time decreases as the children grow older. Write the appropriate null and…

In a study of 2000 model cars, a researcher computed the least-squares regression line of price (in collars) on horsepower. He obtained the following equation of this regression line: Price = -7000 + 170 horsepower Based on the least-squares regression line, what would we predict the cost of a 2000 model car with horsepower equal to 230 to be (assuming no extrapolation error). Please show calculations as tutorial on how to answer the question.
Write down the formula of least square regression line?
Explain about the least square regression line?
The CSV file modeldata.csv contains 200 observations of 4 explanatory variables (x1, x2, x3, x4) and a response variable (y). A multiple linear regression model is built in R using the following code, > modeldata <- read.csv("modeldata.csv") > x1 <- modeldata$x1 > x2 <- modeldata$x2 > x3 <- modeldata$x3 > x4 <- modeldata$x4 > y <- modeldata$y > model <- lm(y~x1+x2+x3+x4) Can you give the R code needed to generate this plot.
