Researchers at the terry college of business at the university of georgia sampled 344 business students and asked them this question: “over the course of your lifetime, what is the maximum number of years you expect to work for any one employer? ” the sample resulted in ¯x = 19.1 years. assume that the sample of students was randomly selected from the 6000 undergraduate students at the terry college and that σ = 6 years. a. describe the sampling distribution of ¯x. b. if the mean for the 6000 undergraduate students is µ = 18.5 years, find p(x¯ > 19.1).c. if the mean for the 6000 undergraduate students is µ = 19.5 years, find p(x¯ > 19.1).
