Answer:
$121,000
Step-by-step explanation:
Mean = $85000
Standard deviation = $2200
55% of mean revenue at the end of the year will be :
0.55 * $2200
0.55 * 2200
= $121,000
Hence, Anna wants to have $121,000 by year end

Answer:
The UCL of the 95% confidence interval for population mean is 10.16 minutes
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 .
That is z with a pvalue of , so Z = 1.96.
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 upper end of the interval is the sample mean added to M. So it is 9.3 + 0.86 = 10.16 minutes.
The UCL of the 95% confidence interval for population mean is 10.16 minutes
Answer:
the answer is i
Step-by-step explanation:
logic
X+x+1+x+2+x+3=74
4x+6=74
4x=74-6
4x=68
x=68/4
x=17
17
17+1=18
17+2=19
17+3=20
