The degree of freedom for t statistic is 11.
According to the given question.
For a repeated-measure study, comparing two treatments with 12 scores in each treatment .
So, we can say that sample size, n = 12.
We know that, when you have a sample and estimate the mean, we have
n – 1 degrees of freedom, where n is the sample size.
Therefore,
The degree of freedom for the given sample test will be
d.f = n -1
⇒ d.f = 12 - 1
⇒ d.f = 11
Hence, the degree of freedom for t statistic is 11.

Answer:
1000 readers
Step-by-step explanation:
40 people represent 4% of the total number of readers.
4% is 1/25 of 100%, therefore:
4% x 25 = 100%
So, if we multiply the number of people that represent 4% by 25, we will get the total number (100%).
40 x 25 = 1,000
The newspaper has 1000 total readers.
Alternatively, you could also divide 4% (40) by 4 which would give you 1%=10. Multiply this by 100 to get 100% which gives us: 100% = 1000.
Hope this helped!
