1) With a normal probability distribution curve, identify which statement is false:

           

>all the possible probabilities are under the curve.

                 

>the area under the curve is <1

                 

>the left side is a mirror image of the right side of the curve

                       

>the probability that an item could have 5 grams less weight and 5 grams more weight is the same.

2) Asymptotic is the term used to show that the tails of a normal distribution:

                 

>approach 1

           

>approach 0

                 

>approach the x-axis

                       

>approach the y-axis

3) If the mean, median, and mode are equal and located in the center of a distribution, then we called this distribution:

                 

>exponential

                 

>uniform

                 

>geometric

                       

>normal

4) With a normal distribution curve, the larger the standard deviation the more narrow the peak of the curve. (True or False)

>True

> False

5) The ratio of two variables converted to a percentage is called ____________.

Which of the following is false? The normal distribution is defined by two parameters, the mean and the standard deviation. In a normal distribution, the probability that the random variable X takes a particular value is zero. For a continuous random variable the probability associated with any values of the random variable is found by calculating the area under the relevant normal curve. For a normal distribution, approximately two thirds of the observations will fall within two standard deviations either...
