To make sure sandwiches from Subway are actually 12 inches long,a team conducted a survey in which they measured the length of 20sandwiches from 10 different Subways. The average length of thesandwiches are 11.8 inch with a sample standard deviation value of0.2 inch. Assuming that this survey can be considered a simplerandom sample and the data follows a normal distribution, what isthe probability that, the length of a sandwich is between(11.9-11.95)?
