use r languege
Explore the sensitivity of the bootstrap estimate of the standard error of the slope estimate using the “boot” procedure, using the hardwood data.
• Run the boot procedure 10 times with a bootstrap sample size of 10.
• Run the boot procedure 10 times with a bootstrap sample size of 100.
• Run the boot procedure 10 times with a bootstrap sample size of 1000.
How does the variability of the bootstrap estimate of standard error change as the number of bootstrap samples increases?
