Two phone batteries are to be tested for how they last (i.e., lifetime). Phone battery A has a lifetime that is normally distributed with mean 4.1 and standard deviation 1.6. Phone battery B has a lifetime that is normally distri mean 3.7 and standard deviation 1.5. Suppose that 100 batteries of each kind are tested. Hint: for this problem, you may find your notes from chapter 5 and 6 useful. (a) By the Central Limit Theorem, A is normally distributed with mean [ and standard deviation (b) By the Central Limit Theorem, B is normally distributed with mean (c) By the Central Limit Theorem, A - B is normally distributed with mean and standard deviation and standard deviation

Two phone batteries are to be tested for how they last (i.e., lifetime). Phone battery A has a lifetime that is normally distributed with mean 4.1 and standard deviation 1.6. Phone battery B has a lifetime that is normally distributed with mean 3.7 and standard deviation 1.5. Suppose that 100 batteries of each kind are tested. Hint: for this problem, you may find your notes from chapter 5 and 6 useful. (a) By the Central Limit Theorem, A is normally distributed with mean (b) By the Central Limit Theorem, B is normally distributed with mean (c) By the Central Limit Theorem, A - B is normally distributed with mean (d) Calculate P(A - B > 0.36) and standard deviation and standard deviation and standard deviation
