Bootstrap t confidence interval for time spent watching
Chapter , Problem 16.24(choose chapter or problem)
Bootstrap t confidence interval for time spent watching videos on a cell phone. Return to or re-create the bootstrap distribution of the sample mean for the eight times spent watching videos in Exercise 16.10 (page 16-12). (a) Although the sample is small, verify using graphs and numerical summaries of the bootstrap distribution that the distribution is reasonably Normal and that the bias is small relative to the observed x. VIDEO (b) The bootstrap t confidence interval for the population mean m is therefore justified. Give the 95% bootstrap t confidence interval for m. (c) Give the usual t 95% interval and compare it with your interval from part (b).
