Daisy asked: Battery Power Problem. A certain type of thermal battery
for an airplane navigation device backup power has a
mean life of 300 hours with a standard deviation of 15
hours. What proportion of these batteries can be
expected to have lives of 322 hours or less? Assume a normal
distribution of backup power device lives.

How do you change the back up battery on a TI-89 Titanium calculator? I can’t figure it out! And I don’t know where my manual is. I can’t find one online either. Can anyone help?
