26. Fred is constructing a 95% condence interval to estimate the average length (in minutes) of movies he watches. His random sample of 15 movies averaged 114 minutes long with a standard deviation of 11 minutes. What critical value and standard error of the mean should he use? A) t* = 2.131,SE = 2.84 B) t* = 2.131,SE = 2.94 C) t* = 2.131,SE =11 D) t* = 2.145,SE = 2.84 E) t* = 2.145.SE = 2.94
