Suppose you wish to test if a number cube (die) is loaded or not. If the die is not loaded, the theoretical probabilities for each roll should be:
|
1 |
2 |
3 |
4 |
5 |
6 |
| 16 2/3 % | 16 2/3 % | 16 2/3 % | 16 2/3 % | 16 2/3 % | 16 2/3 % |
You roll the die 83 times and come up with the following
distribution:
|
1 |
2 |
3 |
4 |
5 |
6 |
| 12 | 11 | 19 | 12 | 15 | 14 |
(Dont need to show work just answer)
What type of test should be used in this situation and what is the
test statistic?
a) One proportion z test; z = 2.140
b) χ2 Goodness of Fit; χ2 = 3.096
c) One proportion z test; z = 0.085
d) χ2 Goodness of Fit; χ2 = 4.074
e) Two proportion z test; z = 0.085
f) None of the above
Homework Answers

2. A player in a dice game suspects that one of the dice is loaded. (A loaded die is one in which the numbers do NOT have an equally likely chance of being thrown.) The player throws the die 400 times and records the outcome of each throw. The results are shown in data set 12_122. Following the directions given in the 12.1 lecture, open the 12_1 22 data set in StatCrunch and perform a goodness- of-fit test, then answer...
