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).
The area of a parallelogram is found using the equation:
where a is the area, b is the base, and h is the height. Substitute the known values into the equation.
Solve for b.
The base of the parallelogram is equal to 4.
I don't know if this is the right answer though lol
