Hello,
You have to know this property:
Answer:
9.5
Step-by-step explanation:
1. Arrange in ascending order
4 5 6 7 8 9 10 11 12
2. Upper Quartile formula:
3×(N+1)÷4
3. Number of terms (N) = 9
4. Apply:
3×(9+1)/4
=3×10/4
=30/4
=7.5th term
5. 7.5th term is the average of the 7th and the 8th term so
Take average
7th term is 9 and 8th term is 10
6. Find average of 9 and 10 = 9.5
7. ANSWER : THE UPPER QUARTILE IS 9.5 FOR THE GIVEN DATA
Answer: 1.6 Ounces.
16/2 is 8.
8/5 is 1.6
You can check this by multiplying 1.6 times 5 then by 2,
The answer is 6.55, because 42.6-(13.45+9.5)=19.65, and 19.65/3=6.55.
