X ~ ( Mean, 2.15) ( Suppose we do not have information of Meanof the population) Question1-----------------------------------------------------------------------------Use calculator go to math---> PRB-------> random sample 1. *Pick one (only-one) sample size of 5 (As we did in lab 2) **calculate Mean of this sample and use the S.D. = 2.15/ sqrt(5) ***Calculate EBM **** Find C.I. for mean at 95% C.L. 2. Repeat thesame process for n=10 and n = 20 3. Study what happened toConfidence Interval when we increased the sample size. Question2-------------------------------------------------------------------------------------------------4. * Find C.I. For n=20 for C.L. 90% ** Study what happened toConfidence Interval when we increased and C.L. from 90% to 95%Question3----------------------------------------------------------------------------------------From the previous lab we know mean for recipe data was 3.57. Writea comment about what you notice in Question 1 and Question 2
