Answer:
The 95% confidence interval for the mean score is:
∈ 
Step-by-step explanation:
We want to estimate the population mean, that is, the average score of all the subjects.
An estimator for the population mean μ is 
Since the sample size is
then we use the statistic
with
degrees of freedom
The confidence interval for the mean is:

Where
is the average score of the sample
is the standard deviation of the sample
is the sample size
for a confidence level of 95% and 26 degrees of freedom
Then confidence interval is

The expression represents the price you paid per gallon is:
- Price paid per gallon =

Step-by-step explanation:
To identify the expression is right, I'll show you with an example: suppose that you paid $56 buying 7 gallons of gas, now you can replace those values in the expression I gave you:
- Price paid per gallon =

- Price paid per gallon =

- Price paid per gallon = 8
And you can check this value by multiplying the price paid by the gallon and the number of gallons, which you obtain the number of dollars you spent:
- <u>Number of dollars (d) = 8 * $7 = $56 </u>
Answer:
Step-by-step explanation:
The inside of a refrigerator is 17 x 18 x 42 inch, to calculate the samples that would fit in the refrigerator is calculating the volume which is length x breadth x height
You can opt to calculate the volume in inch ^3 or cm^3
Both will be discussed here
In inch^3
Volume= 17 × 18 × 42 = 306 x 42= 12852in ^3
In cm^3
Convert inch to cm
I inch is 2.54cm
17 inch = 43.18cm
18 inch = 45.72cm
42 inch = 106.68cm
Volume = 43.18 × 45.72 × 106.68 = 210606.546528cm^3
210606.55cm^3 approximately
