Answer:
The upper confidence limit of a 92% confidence interval for the population mean of grade point average is 2.93.
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 upper end of the interval is the sample mean added to M. So it is 2.89 + 0.04 = 2.93.
The upper confidence limit of a 92% confidence interval for the population mean of grade point average is 2.93.
Answer:
12
Step-by-step explanation:
add the numbers to get the total then divide the total by the amount of columns/numbers.
12 + 12 + 18 + 6 = 48
48 / 4 = 12
110000 is the total dividends of both preferred stock and common stock
So we need to find the dividend per share common stock
First find the total dividends of preferred stock
5,000×2.38=11,900
Subtract the total dividends of preferred stock for the total dividends to find the total dividends of common stock
110,000−11,900=98,100
Finally divide the total dividends of common stock by the number of common stock to find the dividend per share of common stock
98,100÷12,000=8.175....answer
Hope it helps!
Answer:
One thing for sure is that there is a reflection along the x-axis
Step-by-step explanation:
Then 1/3 equals -3 because half of 2 is one
