A sample of 61 bottles of chemical solution is obtained
Chapter 8, Problem 8.1.13(choose chapter or problem)
A sample of 61 bottles of chemical solution is obtained and the solution densities are measured. The sample mean is x =0.768 and the sample standard deviation is s =0.0231. Find the value of c for which (c,) is a one-sided 99% t-interval for the average solution density . Is it plausible that the average solution density is less than 0.765?
