Reference no: EM1314058

A new report claims that 45% of enlisted personnel who have spent at least 4 years and no more than ten in service complete a bachelor's degree, 25% complete some college work, 15% don't seek extra college-level training, and 15% are not accounted for. You wish to see how frequencies determined in population compare with particular local Navy base, so you take easy arbitrary sample of 500 enlisted sailors who have finished between 4 and 10 years in Navy. You determine that 275 completed college degree, 88 have completed some college work, 37 have not required extra college-level training, and rest of the sailors arn't accounted for. How does your sample compare to what you expected to determine?

a) To see how your local Naval base compares to report of all enlisted workers, you will use a

b) Define null hypothesis.

c) Explain how statistics for test you have selected.

d) Are results statistically important? Explain why or why not?
