the two data files are provided in the comments

provided step by step explanation and R code

Please answer these two questions using R code 1. Please answer question 2.16 2.16 Textbook prices. Exercise 1.44 examined data on the price and number of pages for a random sample of 30 textbooks from the Cal Poly campus bookstore. The data are stored in the file TextPrices and appear in Table 1.5. mm TxtPrc a. Perform a significance test to address the students' question of whether the number of pages is a useful predictor of a textbook's price. Report the hypotheses, test statistic, and P-value, along with your conclusion. b. Find and interpret a 95% confidence interval for the slope of this regression model. Also explain what this slope coefficient means in the context of these data.2. Please answer question 1.36 Here is the data provided in the Pines.csv https://docs.go ogle.com/spreadsheets/d/1TnsAMOF2fodo75qs|BFjPM 1wX8wkl9HfOvftqdBrCB4/edit?usp=sharing 1.36 Pines: 1997 versus 1990. Refer to the Pines data described in Exercise 1.35. Examine the relationship between the initial seedling height and the height of the tree in 1997. Pines a. Construct a scatterplot to examine the relationship between the initial height in 1990 and the height in 1997. Comment on any relationship seen. b. Fit a least squares line for predicting the height in 1997 from the initial height in 1990. c. Are you satisfied with the fit of this simple linear model? Explain
