1)  Normal distribution A distribution that takes on the shape of                                                                                               a bell curve.

2) Standard Normal distributionA normal distribution with a mean                                                                                                                                                                                            0  and a standard deviation of 1.

3) deviation  difference between any value and the mean of

                                               the  set.

4) frequency distribution organizes data into categories called

                                                     classes.

5) range difference between the smallest term in the data and      

                          the  largest term in the data set.

6) standard deviation square root of variance.

7) Variance square of the standard deviation.

8) z-score deviation of a value x from the mean of the sample

                                    divided by the standard deviation.

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.
