hey tutor, I have trouble with this question, could you solve it for me? thanks!

Flapper skates (4 points) A team of researcher from Scotland working on flapper skate diving behaviour collected data on deploying 100 diving loggers on different individuals across 4 locations. They collected the depth of the animal in meters, coded "depth", the water temperature in degree Celsius, "temp", the water salanity in part per thousands, \"sal" and the location "lochs" Please provide R Code needed for the following statement. If the a function is part of a package that need to be loaded please also indicate it. Question 6 (0.5 points) A. Fit a linear model predicting the depth as a function of only linear and additive effects of temperature, salinity and locations: 6/ Question 7 (0.5 points) B. Estimate the probability associated with the test of the 3 null hypothesis from the previous model Question 8 (0.5 points) C. Get the effect sizes from the model 6/ Question 9 (0.5 points) D. Check collinearity problem Q/ Question 10 (0.5 points) E. Check model assumption graphically 6/ Question 11 (0.5 points) F. Formal test to check the distribution of the residuals Q/ Question 12 (0.5 points) G. fit a model investigating the fact that the temperature and salinity effects on depth vary per locations Question 13 (0.5 points) H. compare the models with and without interactions fitted at A and G 4/
