Answer:
The 95% confidence interval for the population mean is between $140.89 and $159.11.
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 150 - 9.11 = $140.89
The upper end of the interval is the sample mean added to M. So it is 150 + 9.11 = $159.11
The 95% confidence interval for the population mean is between $140.89 and $159.11.
You have to look it up, but there are are 128 fluid oz in one gallon.
Then find the amount of juice you have total (in fl oz) in the 35 cups
35 * 12 fl oz = 420 fl oz
Then divide by the number of fl oz in one gallon to find the number of gallons
420 fl oz / 128 fl oz = <span>3.28 gallons</span>
