An endocrinologist was interested in exploring the relationship between the level of a steroid (y) and age (x) in healthy subjects whose ages ranged from 8 to 25 years. she collected a sample of 27 healthy subject in this age range. the data is located in the file problem01.txt, where the first column represents x = age and the second column represents y = steroid level. for all r programming, print input and output codes and values, data to be used is below.
(create a quadratic regression in r. write down the fitted equation, multiple r2, and the p-value for β1 from the summary()output.
yi =β0 + β1xi + β2xi2 + εi

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y < 4x − 8 y is greater than or equal to negative 5 over 2 times x plus 5 part a: describe the graph of the system, including shading and the types of lines graphed. provide a description of the solution area. (6 points) part b: is the point (5, −8) included in the solution area for the system? justify your answer mathematically. (4 points)
