### To estimate the standard errors of the coefficients beta0 and beta1 using bootstrap methods, we can follow these steps: Load the data from the Excel file into Python using a library such as pandas. Define a function that takes in the data, randomly samples it with replacement to create a bootstrap sample, fits a linear regression model to the bootstrap sample, and returns the coefficients beta0 and beta1. Use a loop to generate a large number of bootstrap samples (e.g., 1000), and store the coefficients beta0 and beta1 for each sample. Calculate the standard errors of beta0 and beta1 using the bootstrap samples, which can be estimated as the standard deviations of the bootstrapped coefficients
