It is not a graded question but a sample question. Can you answer it LetA =1 S-1 -S -1-1 -1-SStudy how the nullspace of A, denoted Nul A depends on the parameter s. For which values(if any) is the nullspace of A: (i) a line through the origin? (ii) a plane through theorigin? (iii) the origin only? Find an equation of the plane in case (ii).of sRemark. This is a bonus problem. Note that only correct computations and correct answerswith motivation will give credit (in particular, you may not receive partial credit if the compu-tations are wrong). So, be concentrated.

240 students responded to the imaginary student canteen survey. The survey asked whether the student chose a meat or vegetable dish for lunch. In addition, we asked for an opinion on the quality of the food on a scale of 1-5, where 1 means the worst and 5 the best. 131 of the students chose vegetarian food and 109 meat food. Of those who chose vegetarian food, 17 students gave a grade 1, 25 students gave a grade 2, 38 students gave a grade 3, 35 students gave a grade 4, and 16 students gave a grade 5. Of those who chose the meat dish, 14 students gave a grade 1, 29 students gave a grade 2, 42 students gave a grade 3, 20 students gave a grade 4, and 4 students gave a grade 5. Use the function chisq.test() to test the null hypothesis that the choice of lunch is not connected to the opinion about the quality of the food. What is the p-value? Give the answer to three decimal places. Remember the correct decimal separator.
