2. 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?

Chapter 6, Section 2-CI, Exercise 100 Standard Error from a Formula and a Bootstrap Distribution Use Statkey or other technology to generate a bootstrap distribution of sample means and find the standard error for that distribution. Compare the result to the standard error given by the Central Limit Theorem, using the sample standard deviation as an estimate of the population standard deviation. Mean commute time in Atlanta, in minutes, using the data in CommuteAtlanta with n = 500,T-29. i î,...

Research question: In the population of all American adults, how strong is the relationship between age and reaction time? Data were collected from a representative sample of 500 American adults concerning their ages (in years) and reaction times (in milliseconds). What procedure should be used to estimate the strength of this relationship in the population? CI for single mean CI for single proportion CI for difference in means CI for difference in proportions CI for correlation 2Research question: To what...
