Step-by-step explanation:
The correct order to determine if the results are significant are as follows:
1. Randomly separate the employee's individual results into two groups.
2.Calculate the mean of each group.
3. Calculate the difference of the means
4. Run the experiment many times
5. Calculate the probability of a difference of 5.
These steps are used to determine statistical significance by finding difference of means.
Answer:
15.2%
Step-by-step explanation:
There are 12 marbles in total and there are 5 red marbles, so the probability of getting a red marble is 5/12. There are now 11 marbles and there are 4 blue marbles. So the probability of getting a blue marble is 4/11.
You multiply these 2 values together.
5/12 * 4/11 = 20/132 = 0.1515
This is about 15.2%
