A brand batteries will be tested to see if their average life span is more than 60 hours. For this purpose, a sample of 100 units was observed and the average of the sample was 65 hours and the standard deviation was calculated as 10 hours. For the 99% confidence level in testing the duration of the A brand batteries; What is the null hypothesis in this test? O A) HO: u* 00 O B) HO : H> 80 O C) Higbiri- Non of them O D) HO: p= 60
