Assume the population is normally distributed. Click here to view the t-distribution table. Click here to view page 1 of the normal table. Click here to view page 2 of the normal table. Which sampling distribution should be used and why? O A. Use a normal sampling distribution because the population is normal, and a is unknown. B. Use a t-sampling distribution because the population is normal, and o is unknown. O C. Use a t-sampling distribution because n 30. F. Use a t-sampling distribution because the population is normal, and a is known. State the appropriate hypotheses to test. O A. Ho: H=24 OB. Hop# 24 Haj J #24 H : J = 24 O C. Ho: HS24 O D.
