Quiz 1 to 10
5 + 4 ÷ 1 =
Answers are:-
Q1: 9
Q2: 2400
Q3: 63338
Q4: 10880
Q5: 1420
Q6: 0.4
Q7: 24
Q8: $408.04
Q9:
In the data set, 6, 8, 1, 9 and 4, what is the variance?
8.2
Proof for it?
mean = (6+8+1+9+4) / 5 = (14+10+4 ) /5 = 28/5 = 5.6
so variance = sum of (x-mean)^2/ N for a complete set of data
but if you treat this as a sample ,
variance = sum of (x-mean)^2/ (N-1) for a sample of data
If you treat this as a complete data set then:
Variance = ((6-5.6)^2 + (8-5.6)^2 + (1-5.6)^2 + (9-5.6)^2 + (4-5.6)^2 ) / 5
Variance= 8.24
Q10:
If 1/2 of 5 is 3, then what is 1/3 of 10?
4
Proof
If 1/2 of 5 is 3 and what will be 1/3 of 10 is equal to ?
Then the answer is following:-
1/2 of 5 is 3 it means that 1/2 is equal to 60%
Then 1 is equal to 120%
It means 1/3 is equal to 120/3 =40%
So 40% of 10 will be 4
So answer is 4☺
