1)When a fair 6-sided dice is rolled 10 times, the resulting face values are as follows: 1, 2, 6, 5, 5, 6, 3, 4, 5, 1. After conducting the experiment, the researcher claims that . This is an example of ______________ probability.

 

 

2.The probability of rolling a 3 with a single six-sided die is 1/6. The probability of rolling a 5 on a single six-sided die is 1/6. Thus the probability of rolling a 3 and then a 5 on back to back rolls of a six-sided die is  . We can perform this calculation because rolling a 3 and then a 5 are: _____________________ events.                      

3.The probability of rolling a 2 with a single six-sided die is 1/6. The probability of rolling a 3 on the same die is 1/6. Thus, the probability of rolling a 2 or a 3 on any given roll is  . We can perform this calculation because rolling a 2 or a 3 are: ____________________events.                    

 

4.The measure of central tendency that is found by adding all data values and dividing by the total number of data values is called the          ________.

 

 

5.The median of 6 people in a meeting is 25 years. One of the people, whose age is 34 years, leaves the room. The new median is:

 

a. 30                                 b. 50              

c. 40                                 d. It cannot be determined by the information provided

 

 

6.Which of the following is the MOST accurate definition of standard deviation

 

a.     The average of a set of scores

b.     The typical amount by which scores differ from the mean of a set of scores

c.      The average of the sum of squared deviations from the mean

d.     The mean absolute deviation of the sum of the squared deviation from the average

 

7. Calculate the variance for the data set: 2, 2, 4, 6, 6
