True or False: The graphical form of the probability distribution for a continuous random variable X is a smooth bell-shaped curve.

(a)  

True or False: The total area under the normal curve and below the vertical axis is equal to 100%.

(a)  

True or False: The distance from one integral standard score to the next score is given by the mean

(a)  

True or False: The central limit theorem shows that its mean is equal to the population mean, 𝜇 = 𝜇_𝑥̅.

(a)  

True or False: It will tend to have a normal distribution in central limit theorem, regardless of the shape of the population.
