Answer:
The 90% confidence interval for the population mean iron concentration is between 0.167 cc/m³ and 0.195 cc/m³.
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 0.181 - 0.0140 = 0.167 cc/m³.
The upper end of the interval is the sample mean added to M. So it is 0.181 + 0.0140 = 0.195 cc/m³.
The 90% confidence interval for the population mean iron concentration is between 0.167 cc/m³ and 0.195 cc/m³.
The answer is C(-2, 6).
I think you forgot the y in the first equation (with the -4.
Answer:
Part A
3 Bathroom and 3 Kitchen
Part B.
$13,500
Step-by-step explanation:
Bathroom per day = 3
Average profit of Bathroom = $1,200 per hour
Kitchen per day = (12 hours - 3 hours)/3 = 3 kitchen
Average Profit from Kitchen = $3,300 / 3 = $11,00 per hour
As the company cannot do more than 3 bathrooms which has higher per hour average profit, the remaining 9 hours will be utilized for Kitchen Installation.
Part A.
Company will do 3 Bathrooms and 3 Kitchens in order to maximize the profit under given condition.
Part B.
Total Earning = ($1,200 x 3 ) + ($1,100 x 9 ) = $3,600 + $9,900 = $13,500
The company will earn Average profit of $13,500.
Answer:
∠ S = 28°
Step-by-step explanation:
Complementary angles sum to 90°, that is
∠ R + ∠ S = 90°, substitute
62° + ∠ S = 90° ( subtract 62° from both sides )
∠ S = 28°
