In the past.The mean running time for a certain type of flashlight battery has been 9.8.The manufacturer has introduced change in the production method and wants to perform a hypothesis test to determent whether the mean running time increased as a result the hypotheses are; Ho;U=9.8 Ha:U>9.8

suppose that the results of the sampling lead to rejection of the null hypothesis.Classify that conclusion as a type 1 error,a type 11 error or a correct decision,if in fact the mean running time has not increased. A. Type 1 error b.Type 11 error c. correct decision d. can not be determined
