Answer:
Cost of rug during sale = $140
Step-by-step explanation:
Given
Marked price of rug in a store = $200
The store is holding a sale and offering a flat 30% less on marked price on all items
This means the sale price of all items would decrease by 30%
We can calculate the discount offered by taking out percentage discount of the marked price.
Discount offered on rug = 30% of Marked price 
The discount is then subtracted from the marked price to get the price of rug during sale.
∴ Price of rug during sale = Marked price - Discount 
Answer:
Sample
Step-by-step explanation:
The term that represents the description in the question is called sample.
Take for instance:
- 40 students selected from a class of 100
- 1000 people selected from a population of 100000
In the above descriptions:
40 and 1000 represent the samples while 100 and 100000 represent the populations, respectively.
Another example is when 10 cats are picked from an animal farm in order to study their eating pattern.
All these and many more represent sample.

Student 1 2 3 4 5 6 7 8
Marketing 82 86 74 93 90 76 87 100
Finance 76 91 70 79 96 70 85 81

We are given the grades of two different subjects for same student
We perform the paired t test because the final grades for the Marketing and Finance is taken for the same student.
So, Option B is correct
Hence Paired samples t- test is appropriate for Dean's hypothesis
