Question 4 6 pts Question 3e. Choose the following statements that are true about constructing the 90% bootstrap CI for mean cherry tree girth from the sample of 31 observations in the trees data set. The point estimate for the average girth (mu_g) is 13.24839 O The point estimate for the average girth will always be in the center of the bootstrap CI O The approximate standard error of Xbar is 3.138 O We know that the bootstrap Cl contains the true average girth of cherry trees. O the bootstrap=function() code must be in the .Rmd file for it to knit correctly ( we get our critical values for the bootstrap t CI from the qt() function
