The fill in bottles of a wine is normally distributed with mean ? = 750 millilit

Question

The fill in bottles of a wine is normally distributed with mean ? = 750 milliliters (ml) and standard deviation of ? = 9 ml.

1 For samples of size n = 64 bottles selected from this population, the mean of the sampling distribution of x? is _____ and the standard error of x? ______.


a E(x?) = 93.75 se(x?) = 9





b E(x?) = 750 se(x?) = 9





c E(x?) = 750 se(x?) = 0.141





d E(x?) = 750 se(x?) = 1.125
















2 The probability that the mean of a sample of n = 64 bottles falls between 748 and 752 ml is,
P(748 < x? < 752) = _____.


a 0.9500








b 0.9250








c 0.8165








d 0.7154
