TRUE OR FALSE4. Given a normal population with m = 125, s = 15 and n = 25, the P(x-bar


TRUE OR FALSE     4. Given a normal population with m = 125, s = 15 and n = 25, the P(x-bar > 127) = 0.2514.        5. If floodlight life is normally distributed with mean 3500 hours and standard deviation of 200 hours,            then the proportion of those lasting longer than 4000 hours is 0.062.        6. It is correct to say that the standard error of the mean is also the standard deviation of a            sampling distribution of means.        7. P(-0.5
