Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses?
B. Ho: µ+60 seconds
H1: µ= 60 seconds
A. Ho: µ = 60 seconds
H1: µ> 60 seconds
C. Ho: µ = 60 seconds
D. Ho: µ = 60 seconds
H1: µ # 60 seconds
H1: µ< 60 seconds
Determine the test statistic.
(Round to two decimal places as needed.)
