A soft-drink bottle vendor claims that its process yields bottles with a mean internal strength of 157 psi (pounds per square inch) and a standard deviation of 3 pši and is normally distributed. As part of its vendor surveillence, a bottler strikes an agreement with the vendor that permits the bottler to sample from the vendor's production to verify the vedor's clain. a) suppose the bottler randomly selects 15 bottles to sample. What is the mean and standard deviation? b)suppose it's not normally distributed. What is the mean and standard deviation for 64 randomly selected bottles?
