Answer:
C. (36337.32, 48968.68)
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find M as such
In which 
is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 42653 - 6315.68 = 36337.32.
The upper end of the interval is the sample mean added to M. So it is 42653 + 6315.68 = 48968.68.
So the correct answer is:
C. (36337.32, 48968.68)
Answer:
$126,980
Step-by-step explanation:
Given the equation C = 2.32N + 34,180 where 'C' is the cost of raising a child and 'N' is the income. If the Corlone family has an income of $40,000, you can use this value for 'N' and solve for 'C':
C = 2.32(40,000) + 34,180
C = 92,800 + 34,180
C = $126,980
Answer:
$33 per hour
Step-by-step explanation:
"Time and a half" means the overtime rate is 1 1/2 times the base rate.
overtime rate = (1 1/2) × $22/hour = $(22 +1/2(22))/hour = $33/hour
The correct overtime rate is $33 per hour.
I can help you with #20. For example, lets say 3/5, this fraction would be made up of 5 parts and 3 are covered, which doesn't make it full, if it was 5/5 it would be full. When you do something with a reciprocal you turn it over, so 3/5 would be turned over to 5/3, thus making it a whole number
