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 answer is C. Reflection
hope this helps !
The slope is 1 and there is no y intercept.
$58.08 I think that’s what I got when I typed it in the calculator
Answer: the answer is 150 :)
Step-by-step explanation: Volume of a cone is
V = 1/3 pi * r^2 *h
The volume of one cone is
pi = 3.14
r = d/2 = 6/2 =3
h=9
Substitute what we know
V = 1/3 * (3.14) * (3^2) * (9)
= 27* 3.14
= 84.78 cm^3
The water cooler has 12717 cm^3 water
Divide the water by the volume of the paper cup cone and we will know how many paper cup cones we can fill, assuming we fill them completely.
12717/ 84.78 = 150
We can fill 150 paper cup cones. have a great day!
