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:
Y
opportunity cost
Step-by-step explanation:
The Production Possibilities Curve, shows the maximum combinations of two goods a theoretical economy can produce with the current state of technology and given the available resources.
Any increase in the production of one commodity must be done at the expense of the other, the opportunity cost of the good increased is the number of unit of the other that we have to give up.
in this question the opportunity cost of producing 10 more unit of good X is the 5 units of good Y that was given up.
Convert 2/5 to a decimal and you get .4, or 40%. 40% of the band members also sing, so yes, the band has the same number of string instrument players and singers.
