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.
