Answer:
The 95% confidence interval for the true population mean dog weight is between 62.46 ounces and 71.54 ounces.
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 67 - 4.54 = 62.46 ounches.
The upper end of the interval is the sample mean added to M. So it is 67 + 4.54 = 71.54 ounces.
The 95% confidence interval for the true population mean dog weight is between 62.46 ounces and 71.54 ounces.
Answer:
62
Step-by-step explanation:
Answer: option C) 2,500 ml (under the assumptions shown below)
Explanation:
This is a conversion of units, but you missed the unit of the question.
What is it?
It seems it should be 2.5 liters.
So, I am going to explain you how to deal with this problem, assuming you have to find the measure equivalent to 2.5 liters.
All the choices are in mililiters (ml).
Then, you use the conversion factor 1 liter = 1000 ml
With that you do:
2.5 liter × 1000 ml / liter = 2,500 ml
And that is the choice C).
Answer:
A=2, B=10, C=-18
