Answer:
1/3
Step-by-step explanation:
anything James did is to distract you. they are independent events. there are three colours, so it has a 1/3 chance of landing on any of them, unless one side is bigger than the others
Answer:
The right options are:
a. The margin of error is 0.632
f. There is a 95% chance that the true mean is between 11.968 and 13.232 minutes.
Question: select one or more correct options.
Step-by-step explanation:
The margin of error can be calculated from the upper and lower bounds of the confidence interval as:
E = (UB - LB)/2 = (13.232-11.968)/2 = 1.264/2
E = 0.632
As the confidence interval is calculated at 95% confidence, we are 95% confident that the true mean is within the calculated interval. So, there is a 95% chance that the true mean is between 11.968 and 13.232 minutes. Although we are not 100% confident (that's why Option d is false).
Also, this interval does not give us information about the sampling distribution (option e is false).
Answer:
GCF: 4
Step-by-step explanation:
The factors of 12 are: 1, 2, 3, 4, 6, 12
The factors of 20 are: 1, 2, 4, 5, 10, 20
Then the greatest common factor is 4.
