On the computer, draw 1000 bootstrap samples of size 5 from the distribution of 173 values of ln(alcohol DR [diet record] + 1) in the Data Set VALID.DAT, where alcoh_dr is the amount of alcohol consumed as reported by diet record by a group of 173 American nurses who recorded each food eaten on a real-time basis, over four 1-week periods spaced approximately 3 months apart over the course of 1 year. For each sample of size 5, compute the sample mean
where n = 5 and μ0 = overall mean of ln(alcohol DR + 1)
over the 173 nurses = 1.7973.
If the central-limit theorem holds, then what percentage of t-values should exceed 2.776 in absolute value?
