1856.8 I think i could be wrong though
Answer:
The 95% confidence interval for the population mean is between 25.86 and 28.14.
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 the margin of error 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 27 - 1.14 = 25.86
The upper end of the interval is the sample mean added to M. So it is 27 + 1.14 = 28.14
The 95% confidence interval for the population mean is between 25.86 and 28.14.
You have to set up a ratio between the owner's income and the total income so
<u>47</u> = <u>2176.10</u>
53 x
then cross multiply to slove for x
47x = 115333.30
then divide each side by 47
x = 2453.90
the company makes $ 2453.90
I think the answer is 4/12 or 1/3
Answer:
(A) 0.800
(B) 1.000
Step-by-step explanation:
Probability is given by number of possible outcomes ÷ number of total outcomes
(A) Number of possible outcomes = 8, number of total outcomes = 10
Probability (exactly 8 seeds will germinate) = 8/10 = 0.800
(B) Probability (at least 8 seeds will germinate) means either 8 seeds will germinate or more than 8 seeds will germinate
Probability (more than 8 seeds will germinate) = 1 - 0.800 = 0.200
Probability (at least 8 seeds will germinate) = 0.800 + 0.200 = 1.000
