An experiment is designed to measure the time necessary for a robotic lens to adapt to reduced light. We have n=50 observations from the repeated experiments. The sample mean, X¯, was 6.32 seconds and the sample standard deviation, s, was 1.65 seconds. a. Using the central limit theorem, what approximate distribution does X¯−µ σ/√ n follow, where µ is the true population mean and σ is the true population standard deviation? b. Compute an approximate 95 percent confidence interval for the true average adaptation time (µ).
