1/4 = the probability of getting spiral wrapping paper
1/3 = the probability of getting a green ribbon
1/4 x 1/3 = 1/12 = the probability of getting spiral wrapping paper and a green ribbon
Answer: a) (1008.34,1019.658) b) (1009.24,1018.76)
Step-by-step explanation:
Since we have given that
n = 75
mean = 1014 hours
Standard deviation = 25 hours
At 95% two sided , z = 1.96
So, confidence interval would be
(b) Construct a 95% lower confidence bound on the mean life.
z = 1.65
So, confidence interval would be
Hence, a) (1008.34,1019.658) b) (1009.24,1018.76)
Answer:
$208,850 < x <= $372,950
Step-by-step explanation:
You didn't provide all the possible answers. In this case we don't need to see all answers to help you... but because you didn't provide all the choices for answer, we can't give the exact answer, only the possible range of values.
The question asks for a possible taxable income for a couple filing under the 33% bracket.
If we look at the table, we see the 33% bracket is for income ranging from $208,850 (exclusively) to $$372,950 (inclusively)
So, your answer has to be within the range:
$208,850 < x <= $372,950
It cannot be $208,850 but it can be $372,950 and any number in between.
Since you didn't provide the answer choices, we can't tell you if it's A, B, C, D, and so on...
