lizzy,, my recommendation is for you to go to college and not rely on yahoo answer for question like that... oh by the way(do you think that the problem in east Iran has definite sexual overtones from the sixties) because i do,,at least that's my 95% ESTIMATE if you factor in the Muslim Jesus factor with a half ratio of good sense

A confidence interval of a mean is usually symetrical around the mean, so (44.8+50.2)/2 = 2.7+44.8 = 47.5
